meta-microblaze: toolchains

Resync the microblaze toolchain items to match the latest YP master version.

binutils and gdb are based on the same patch set, but the release version
are based on slightly different sources, thus the patches are a bit
different.

-Subject: [PATCH] gdb/microblaze-linux-nat.c: Fix target compilation of gdb
-
-Add the nat to the configure file
-
-Remove gdb_assert.h and gdb_string.h.
-
-Adjust include for opcodes as well.
-
-Update to match latest style of components, similar to ppc-linux-nat.c
-
-Update:
-  get_regcache_arch(regcache) to regcache->arch()
-  regcache_raw_supply(regcache, ...) to regcache->raw_supply(...)
-  regcache_raw_collect(regcache, ...) to regcache->raw_collect(...)
