This patch restricts the section names matched in coff_section_type,
a function that translates section names to symbol type, and arranges
to translate section flags to symbol type before looking at names.
The latter change resulted in various test failures due to improper
section flags being used in tests, and by the plugin support, so fix
that too.
The new test fails on many ELF targets that lack .init/fini_array
in their scripts. I've just xfailed those. pru-elf oddly defines
__init_array_begin rather than __init_array_start. I've left that
target as a FAIL, and pj-elf too which reports an error for undefined
weak symbols.

* syms.c (coff_section_type): Only allow '.', '$' and numeric
following the standard section names.
(bfd_decode_symclass): Prioritize section flag tests in
decode_section_type before name tests in coff_section_type.
* plugin.c (bfd_plugin_canonicalize_symtab): Init fake_section
and fake_common_section using BFD_FAKE_SECTION. Use "fake" as
their names and choose standard .text section flags for
fake_section.

Oddly, config.sub converts a duple ending in -elf for these target to
-unknown-none, which means they aren't seen as elf targets by
binutils. So, counter that. This exposes a number of testsuite
issues (ones you would have seen if configuring with a full triple,
say m68hc11-unknown-elf).
