package/lbreakout2: fix linking with intl

lbreakout2 doen't build with (e)glibc toolchain when gettext package is selected.

With (e)glibc libintl is provided by the libc whereas with uClibc it's provided by gettext.

Linking with intl is only needed if the toolchain needs gettext and locale is set.
