elf: Copy p_align of PT_GNU_STACK for stack alignment
commit 74e315dbfe5200c473b226e937935fb8ce391489

elf: Set p_align to the minimum page size if possible
may ignore p_align of PT_GNU_STACK when copying ELF program header if
the maximum page size is larger than p_align of PT_LOAD segments. Copy
p_align of PT_GNU_STACK since p_align of PT_GNU_STACK describes stack
alignment, not page size,
PR binutils/29319
* elf.c (copy_elf_program_header): Copy p_align of PT_GNU_STACK
for stack alignment.
