    PR32266, segv when linking libclang_rt.asan-powerpc64.so

    Change the mmap support added with commit 9ba56acee518 to always mmap
    memory with PROT_READ | PROT_WRITE.  Prior to that commit most file
    contents were read into a buffer allocated with bfd_alloc or
    bfd_malloc and thus the memory was read/write.  Even after that commit
    any section contents with relocations must be read/write to apply the
    relocs.  Making them all read/write is not a major change, and it
    should not introduce any measurable linker slowdown for contents that
    are not modified.  More importantly, it removes a BFD behaviour
    difference that only triggers when large files are involved.

            PR 32109
            * libbfd.c (bfd_mmap_local): Remove prot param.  Always mmap
            with PROT_READ | PROT_WRITE.  Adjust all calls.
            (_bfd_mmap_temporary): Rename from _bfd_mmap_readonly_temporary.
            (_bfd_munmap_temporary): Rename from
_bfd_munmap_readonly_temporary.
            _bfd_mmap_persistent): Rename from _bfd_mmap_readonly_persistent.
            (_bfd_generic_get_section_contents): Use PROT_READ | PROT_WRITE
            regardless of relocs.
            * libbfd-in.h: Update decls to suit.  Make non-USE_MMAP variants
            static inline functions.
            * elflink.c: Update all uses of _bfd_mmap functions.
            * elf.c: Likewise.
            (bfd_elf_get_str_section): Revert commit 656f8fbaae.
            * libbfd.h: Regenerate.
