Upstream-Status: Backport [https://sourceware.org/git/?p=binutils-gdb.git;a=patch;h=b6ac5a8a5b82f0ae6a4642c8d7149b325f4cc60a]
CVE: CVE-2025-11494

Since x86 .eh_frame section may reference _GLOBAL_OFFSET_TABLE_, keep
_GLOBAL_OFFSET_TABLE_ if there is dynamic section and the output
.eh_frame section is non-empty.

	PR ld/33499
	* elfxx-x86.c (_bfd_x86_elf_late_size_sections): Keep
	_GLOBAL_OFFSET_TABLE_ if there is dynamic section and the
	output .eh_frame section is non-empty.
