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. bfd/ PR ld/22423 * elf.c (_bfd_elf_map_sections_to_segments): Remove PF_X from PT_PHDR segment. ld/ PR ld/22423 * testsuite/ld-alpha/tlsbin.rd: Replace "R E " with "R +" for PT_PHDR segment. * testsuite/ld-alpha/tlsbinr.rd: Likewise. * testsuite/ld-ia64/tlsbin.rd: Likewise. * testsuite/ld-powerpc/tlsexe.r: Likewise. * testsuite/ld-powerpc/tlsexe32.r: Likewise. * testsuite/ld-powerpc/tlsexetoc.r: Likewise. * testsuite/ld-s390/tlsbin.rd: Likewise. * testsuite/ld-s390/tlsbin_64.rd: Likewise. * testsuite/ld-sparc/tlssunbin32.rd: Likewise. * testsuite/ld-sparc/tlssunbin64.rd: Likewise. * testsuite/ld-elf/pr22423.d: New test.
