ld: Remove PF_X from PT_PHDR segment
It was reasonable to mark PT_PHDR segment with PF_X for compatibility
with UnixWare and Solaris linkers 20 years ago. But it is inappropriate
today when the primary OS of GNU ld is Linux. This patch removes PF_X
from PT_PHDR segment as gold does.
Tested natively on Linux/x86 as well as crosss-binutils for alpha-linux,
ia64-linux, powerpc64-linux, powerpc-linux, s390-linux, s390x-linux,
sparc64-linux and sparc-linux.
