gcc: backport patch to fix data relocation to !ENDBR: stpcpy

gcc: backport patch to fix data relocation to !ENDBR: stpcpy

There is the following warning when building linux-yocto with
default configuration on x86-64 with gcc-14.2:
  AR      built-in.a
  AR      vmlinux.a
  LD      vmlinux.o
  vmlinux.o: warning: objtool: .export_symbol+0x332a0: data relocation to !ENDBR: stpcpy+0x0

This change set removes the warning.
