b5c68b465e Revert "Change the default build-id size from 20 to 16 bytes" 
This reverts commit fe76210da6
because I misunderstood the actual default size of build-id
of the GNU linkers.

d3923b9f27 Weak symbols shouldn't keep as-needed DSOs 
If all references to an DSO are weak, the DSO shouldn't be considered
being used in terms of --as-needed. This is needed for GNU ld compatibility.

1f3931fc9e Do not put non-alloc NOTE section into a PT_LOAD segment 
This bug caused a test failure of Gentoo's dev-lang/go-1.16.4
paackage. Specifically, `go tool dist test testshared` failed
due to this bug.

8219fdd688 Simplify input file priority 
This change is required to build Gentoo's net-libs/libtorrent-0.13.8-r1
package with FEATURES=test, e.g.

  $ FEATURES=test emerge net-libs/libtorrent

02fa969295 Place .ctors and .dtors into .init_array and .fini_array 
This change is needed to build Gentoo's dev-lang/gprolog-1.4.5,
which is the GNU Forth package. GNU Forth creates ELF objects
itself, and it still uses .ctors and .dtors as opposed to .init_array
and .fini_array.

ed98211a24 Allow to refer unversioned symbol within an object file 
Previously, mold couldn't handle an object file which contains
versioned symbol `foo@@SOME_VERSION` that also has an undefined
symbol `foo`. Now, `foo` is resolved to `foo@@SOME_VERSION`.

This change is required to build Gentoo's media-libs/alsa-lib-1.2.3.2-r1
package.

de7ba9014f Add "GNU gold" to the --version string 
The configure script in Gentoo's dev-libs/jansson-2.13.1-r1 package
treats mold 0.1.1 as GNU ld 0.1.1, which is from 1980s if existed.

Adding "GNU gold" to the help message solves the nasty issue, as the
configure script considers any version of GNU gold supports modern
features.
