This patch series upgrades GCC to 16.1 and includes the required
runtime and compatibility fixes identified during testing in OE-Core.

The remaining fixes from v3 are updated in this version with
toolchain-gcc specific handling for libatomic related changes
based on review feedback.

Changes in v4:
- Use toolchain-gcc override for glibc libatomic linker flags
- Use toolchain-gcc override for libc-test libatomic-staticdev dependency

Changes in v3:
- Fix missing Signed-off-by in gn and gcc inner patch files

Changes in v2:
- Add libatomic-dev to elfutils ptest RDEPENDS
- Add libatomic-staticdev to libc-test ptest RDEPENDS
- Package new libcaf_shmem.a static library in libgfortran
- Fix gn build with GCC 16 on musl
- Backport GCC i386 ICE fix with -ffloat-store and SSE [PR125308]

Summary of patches:
- Patch 01: Upgrade GCC to 16.1 release.
- Patch 02: Disable automatic libatomic linking during gcc-runtime build.
- Patch 03: Package new libatomic_asneeded runtime files.
- Patch 04: Avoid passing MULTIBUILDTOP to libatomic in OE builds.
- Patch 05: Fix ICE on i386 with -ffloat-store and SSE [PR125308].
