continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.

Internally used `compiler-rt` had to be fixed for `glibc-2.31`,
basically the same approach as in the LLVM fix
(7137183bbe05738246be2be0e704c1be9bf19947).
As soon as a newer `compiler-rt` is used for `swift`, this patch can be
removed again.
* simplify versioning
* uniform patch documentation
* reorder phases so they read in order
* reorder scripts for readability
* GNU toolchain dir:
handle sysroot for GNU toolchain like for C headers, so that
GCC_INSTALL_PREFIX is actually used correctly
add check phase for running some of the Swift test suite
A small number of tests is failing, which needs investigation,
so the check phase remains disabled by default.
update Swift
* new tweaks to the build process are mostly documented inline
* the swiftc wrapper needs the linker path for libicu
* some older tweaks could be removed
* remove fuzz from patches by updating line numbers
* one build fix to libdispatch has been filed upstream
* necessary tweaks and patches to get swift 4.2.1 to build
* disabled more tests because they would require additional patching
* delete empty directories from final build output
* some minor cleanup
One should do this when needed executables at run time. It is more
honest and cross-friendly than refering to binutils directly, if one
neeeds the default binary tools for the target platform, rather than
binutils in particular.
* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
