returning bfd_reloc_dangerous. Also check that __ImageBase is
defined before accessing h->u.def.

The segfault was a symptom of messing with the absolute section next
field, confusing bfd_section_removed_from_list in linker.c:fix_syms.
That's not all that was going wrong. The INSERT list of output
sections was being inserted into itself, ie. lost from the main
list of linker statements.

* ldlang.c (process_insert_statements): Handle pathological
case of the insert script being inserted before the first
output section statement in the default script.

(insert_os_after): Change parameter to a list union pointer.
(lang_insert_orphan): Test section owner here and adjust
insert_os_after call.

PowerPC ELF always uses bfd_arch_powerpc, so we shouldn't allow the
gas -mpwr, -mpwr2 or -mpwrx options to choose bfd_arch_rs6000.
Given the possible values of ppc_cpu, I think the as_fatal at the end
of ppc_arch will never be reached, so it can be deleted and the code
simplified a little.

* config/tc-ppc.c (ppc_arch): Return bfd_arch_powerpc for ELF.
Delete dead code.

When using a bss-plt we'll always trigger the RWX warning, which
disturbs gcc test results. On the other hand, there may be reason to
want the warning when gcc is configured with --enable-secureplt.
So turning off the warning entirely for powerpc might not be the best
solution. Instead, we'll turn off the warning whenever a bss-plt is
generated, unless the user explicitly asked for the warning.

* elf32-ppc.c (ppc_elf_select_plt_layout): Set
no_warn_rwx_segments on generating a bss plt, unless explicity
enabled by the user. Also show the bss-plt warning when
--warn-rwx-segments is given without --bss-plt.

* bfdlink.h (struct bfd_link_info): Add user_warn_rwx_segments.

* lexsup.c (parse_args): Set user_warn_rwx_segments.

the rwx tests.

In 162c6aef1f ("gas: fold symbol table entries generated for
.startof.() / .sizeof.()") I screwed up quite badly, inverting the case
sensitive and case insensitive comparison functions.
Since 9911806278, the configure checks
about GMP and MPFR for gdb builds have been moved to the toplevel
configure.
However, it doesn't take into account the --disable-gdb option. Meaning
that a build without gdb will require these libraries even if not
needed.
ChangeLog:
* configure.ac: Skip GMP and MPFR when --disable-gdb is
provided.
* configure: Regenerate.
