[PATCH] fix build on nls free systems

I made a patch that detects if libintl.h (needed for nls) is present on the
host system and if it's not, it nls support is disabled by providing
dummies for the used nls functions.

This way if there is nls support on the host system the *config targets
will build according to Arnaldo Carvalho de Melo's i18n modifications, else
it just uses the original English messages.

I have also made a bug report at kernel's bugzilla:
http://bugzilla.kernel.org/show_bug.cgi?id=5501
And there is a discussion about this problem in Gentoo's bugzilla:
http://bugs.gentoo.org/show_bug.cgi?id=99810
