Changelog:

  https://gcc.gnu.org/gcc-15/changes.html

NIOS II support has been removed, and we removed it from Buildroot
some time ago.

AArch64 ILP32 support has been deprecated, but we never supported it
in Buildroot.

In the stack of patches, just keep patch 0001.

Indeed, from 14.2.0:

- 0002-libsanitizer-also-undef-_TIME_BITS-in-sanitizer_proc.patch is
  upstream as of commit fa321004f3f6288d3ee2eefa6b02177131882dca

- 0003-libquadmath-Fix-up-libquadmath-math-sqrtq.c-compilat.patch is
  upstream as of commit 3ac02e67503ccffa3dfeeffc0a60fce6bdaca43b
