* elfxx-ia64.c (elfNN_ia64_relax_section): Assume linker will
always insert 32byte between the .plt and .text sections after
the the first relaxation pass.
* mach-o.c (bfd_mach_o_make_bfd_section): Use the standard ELF name
.eh_frame for __TEXT.__eh_frame so that it is recognized by gdb.
Use shorter sections name for well known sections.
(bfd_mach_o_scan_read_dylinker): Only put dylinker name in the
section content.
(bfd_mach_o_scan_read_segment): Use shorter sections name for
well known segments.
(bfd_mach_o_scan_read_command): Ignore some new commands.
(bfd_mach_o_openr_next_archived_file): Use more descriptive names
for members filename.
(bfd_mach_o_fat_extract): New function to easily extract members
of a fat binary.
* mach-o.h (bfd_mach_o_load_command_type): Add new constants.
(bfd_mach_o_dylinker_command): Fix comment and reindent.
(bfd_mach_o_fat_extract): New prototype.
* libltdl.m4 (_LT_SYS_DYNAMIC_LINKER, _LT_LINKER_SHLIBS):
Add cache variables to tests that require the linker to work.
For shlibpath_overrides_runpath, this also changes the semantics
to let the result from the C compiler take precedence.
