Due to mathvec https://lists.gnu.org/archive/html/info-gnu/2023-07/msg00010.html

* Vector math library libmvec support has been added to AArch64.  It
  requires GCC version >= 10.1.0.  It can be disabled via
  "--disable-mathvec", however that is not a supported configuration as
  it changes the ABI. The symbol names follow the AArch64 vector ABI,
  they are declared in math.h and have to be called manually at this point.

Pull request overview

This PR updates the GCC version used in the bootstrap build from 9.5.0 to 10.5.0 to support glibc 2.39, which requires GCC >= 10.1.0 for AArch64 vector math library (libmvec) support. The update ensures compatibility with the newer glibc version that includes vectorized math functions for ARM64 architecture.

Changes:

  • Updated GCC version from 9.5.0 to 10.5.0 in the build script
  • Updated SHA256 checksum to match the official GCC 10.5.0 release
