Merge ^/vendor/binutils/dist@214571 into contrib/binutils, which brings

us up to version 2.17.50.20070703, at the last GPLv2 commit.

Amongst others, this added upstream support for some FreeBSD-specific
things that we previously had to manually hack in, such as the OSABI
label support, and so on.

There are also quite a number of new files, some for cpu's (e.g. SPU)
that we may or may not be interested in, but those can be cleaned up
later on, if needed.
