RFA: start of i18n

[Tom Tromey <tromey at redhat dot com>]

This patch adds some minor infrastructure required to let gdb use
gettext for message translation.  Basically it works the same way as
gettext does in bfd, gas, ld, etc.

No messages are actually translated at this point.  This just makes it
possible to do so.

This causes no test suite regressions on Red Hat Linux 7.3.

Ok to commit?

Tom
