[Buildroot] [PATCH 1/5] grep: give hints to ./configure on where gettext() is

[Thomas Petazzoni]

The build of grep fails with:

fgrep.o: In function `add_count':
fgrep.c:(.text+0x90): undefined reference to `libintl_gettext'

This is because the ./configure script of grep thought that gettext
was part of the C library instead of part of libintl:

checking for GNU gettext in libc... (cached) yes

Therefore, it forgot to add -lintl while linking grep and related
applications. Passing gt_cv_func_gnugettext_libc=no forces grep to use
libintl instead.
