[Buildroot] [PATCH] package/gcc: add patch to fix gcc 11 build warning

[Brandon Maier via buildroot]

When building GCC 11 with GCC 14 the following error occurs

> ../../../libiberty/simple-object-mach-o.c:1231:17: error: passing argument 1 of 'set_32' from incompatible pointer type [-Wincompatible-pointer-types]

This was fixed upstream in GCC12[1]. It is applied to the GCC 11 release
branch[2], but has not been officially released yet.
