[Buildroot] [PATCH v2] gnupg2: fix linking with intl

[Vicente Olivert Riera]

gnupg2 needs to link with intl if the gettext package is selected.
Otherwise we will see an error like this one:

libgpg-error.a(libgpg_error_la-strsource.o): In function
`gpg_strsource':
strsource.c:(.text+0x4c): undefined reference to `libintl_dgettext'

Fixes:
