Since 03eaa48 added perl.withPackages, there is a canonical way to
create a perl interpreter from a list of libraries, for use in script
shebangs or generic build inputs. This method is declarative (what we
are doing is clear), produces short shebangs[1] and needs not to wrap
existing scripts.
Unfortunately there are a few exceptions that I've found:
1. Scripts that are calling perl with the -T switch. This makes perl
ignore PERL5LIB, which is what perl.withPackages is using to inform
the interpreter of the library paths.
2. Perl packages that depends on libraries in their own path. This
is not possible because perl.withPackages works at build time. The
workaround is to add `-I $out/${perl.libPrefix}` to the shebang.
In all other cases I propose to switch to perl.withPackages.

Reuse the configuration generated by configure.sh to dynamically install
the bindings for all enabled targets. A bit of a hack grepping for the
respective lines in the Makeconf which incidentally also parse as shell.
Alternative would be to check for the target libs.
Besides updating the version, this commit decouples trace-cmd and
kernelshark source revisions. These two programs are developed in the
same repository but are released independently. Nixpkgs built the
previous versions of these programs from the same source commit, which
meant that at least one of the programs were not built from the
officially released version. Now we use the release tags of the
corresponding programs.
Includes the following version changes:
- skalibs: 2.10.0.1 -> 2.10.0.2
- execline: 2.7.0.0 -> 2.8.0.0
- s6-networking: 2.4.0.0 -> 2.4.1.0
- s6-linux-init: 1.0.6.0 -> 1.0.6.1
- s6: 2.10.0.0 -> 2.10.0.2

Hello,
New versions of some of the skarnet.org packages are available.
skalibs-2.10.0.2: bugfixes
execline-2.8.0.0: major version bump, but few and low-impact changes
s6-2.10.0.2: bugfixes
s6-linux-init-1.0.6.1: bugfixes
s6-networking-2.4.1.0: minor version bump
Some details:
* execline-2.8.0.0
----------------
- The if program now propagates its child's exit code by default if it
exits.
- The backtick program's -i behaviour (exit on child failure or
presence of a null character in its output) is now the default. Other
behaviours in case of child failure can be obtained via -I, -x or -D
options; -x is the new one.
- These changes are compatible with all the common uses of if and
backtick, but break compatibility in edge cases, which is why a
major version bump is required. This has nothing in common with the
previous major version bump, which had massive changes all over the
place; this one should go smoothly, and will only impact very specific
uses of backtick.
execline now has man pages, thanks to the untiring flexibeast!
The repository can be found here:
https://github.com/flexibeast/execline-man-pages
Please allow some time for the man pages to be updated to reflect
the current HTML documentation. Currently, the man pages document
execline-2.7.0.1; they are accurate for 2.8.0.0 except for the if and
backtick changes.
* s6-linux-init-1.0.6.1
---------------------
- Bugfixes.
- When s6-linux-init is built with utmps, the default utmp user for
s6-linux-init-maker was set to "utmp". That was a bug: now, by default,
s6-linux-init-maker does not create the utmp services if the -U option
is not given. If you used s6-linux-init-maker without the -U option
and still need the utmps services, you should explicitly set "-U utmp".

git://git.skarnet.org/s6-linux-init
* s6-networking-2.4.1.0
---------------------
- Bugfixes (nothing security-related).
- It is now possible to define a maximum amount of time spent in the
TLS handshake no matter how s6-networking has been built. (The -K
option has been implemented for the libtls backend.)
- When SNI has been required, the TLS-related binaries now export
the SSL TLS SNI SERVERNAME option to their application; the variable
contains the relevant server name.

s6-networking has man pages as well:

Enjoy,
Bug-reports welcome.

Without this change `as` on `aarch64-darwin` is defunct:
```
$ /nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/bin/as -v
/nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/bin/as: assembler (/nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/libexec/as/arm64/as or /nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/libexec/as/arm64/as) for architecture arm64 not installed
Installed assemblers are:

/nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/libexec/as/x86_64/as for architecture x86_64
/nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/libexec/as/ppc/as for architecture ppc
/nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/libexec/as/i386/as for architecture i386
/nix/store/g11xba8ch20zndaf32hfnap46z47b5k3-cctools-port-949.0.1/libexec/as/arm/as for architecture arm
```
Apple defaults to Clang in all cases from what I see, but nixpkgs prefers `cctools`: #51881.
