[WIP] gcc: update to 16.1.1+20260502.

Testing the changes

• I tested the changes in this PR: briefly

[ci skip]

This restricts musl1.1 to specifically armv* architectures rather than all 32-bit architectures since armv* are the only ones officially supported.

I have removed the patches for --enable-autolink-libatomic as support for that was merged into gcc upstream.

I have also enabled libsanitizer for musl architectures.

TODO: libphobos currently fails to build on armv7l-musl and armv6l-musl, I did try reworking the time_t patch for the changes to libphobos but I haven't gotten it working atm. I have removed the patch for now. I can confirm the same issue happens on the latest release of ldc (2.42.x) as well. I have disabled gdc on those architectures temporarily until I have the time to fully debug it.

I also have yet to update the cross compilers (which I will do soon) or run a full test of the core packages as well as anything pulled in by the ISOs, which I will do when I have the time.

Note for merging: glibc and musl must be merged and built before everything else.

@oreo639 What do you think about updating glibc to 2.44 (which has most of the patches here) as well as m4 to 1.4.21 in this PR? I guess everything else can be done separately.

Should be fine. I'll start working on this again later today or tomorrow i.g. (I'm not looking forward to trying to fix the libphobos musl time 32 issue :p)

Also, thanks for the aarch64 testing.
