[PATCH] Define gettext msgid context helpers when NLS is disabled

[Guillem Jover]

When disabling NLS support in configure with --disable-nls, the build
might fail when using the gettext context related helper functions,
due to undefined LC_MESSAGES. Declare them when !ENABLE_NLS.

Another option I guess would be to define LC_MESSAGES to something.
Please review, I've only tested the pgettext function which is the one
we are actually using on dpkg.
