This fixes a few problems in the powerpc ld configury.
1) Using powerpc*le-* to test for powerpcle and powerpc64le would
incorrectly match a target triple like powerpc-apple-elf.
2) In the same vein, *64* could match 64 in the user supplied MANUF-OS
part of the target triple.
3) tooldir vars were missing, and some target aliases would result in
ridiculous values for those tdir_* vars given.
4) Since 2016-04-25, BE support was added automatically when asking
for an LE target. If that is a good idea, then so is adding LE
support when asking for BE.
* configure.tgt (powerpc*-*-linux* et al): Rewrite, adding LE
support for BE. First output all target endian configury
values, then opposite endian. Handle more tooldirs. Fix
bogus matches with strings in MANUF-OS part of target triple.
Add a configure option --enable-relro to decide whether -z relro should
be enabled in ELF linker by default. Default to yes for all Linux
targets, except FRV, HPPA, IA64 and MIPS, since many relro tests fail
on these targets.

The `am34-*-linux*' target cannot be configured for, `am34' is not a CPU
name recognized by `config.sub'. It has never been, required code has
not been contributed to GNU config, neither before nor since the
addition of the target triplet to our configury with commit bfff164249
("Add MN10300 linker relaxation support for symbol differences") back in
2007. Also there is no difference in actual tool configuration between
the `am34-*-linux*' and `am33_2.0-*-linux*' targets, except from a
different executable prefix and tooldir name.
Given the above remove the target triplet from our configuration.

At the moment it is possible to configure binutils for these triples
but the resulting linker defaults to little endian with huge numbers
of testsuite failures, which on the face of it does not appear to make
much sense.
This patch makes the behaviour similar to armeb-elf and the testsuite
is clean.
