[Buildroot] [PATCH v1] libv4l: fix missing libintl linking

[Peter Seiderer]

Add missing libintl linking to utils/dvb and utils/keytable (patch
Makefile.in because patching Makefile.am and autoreconf did not work).

Add proper gettext dependency for v4l-utils option.

Fixes [1]:
 dvb-format-convert.o: In function `parse_opt':
 dvb-format-convert.c:(.text+0x46): undefined reference to `libintl_gettext'

Please patch Makefile.am. To make autoreconf work on this package,
simply add host-gettext to LIBV4L_DEPENDENCIES.

Then, submit the patch upstream, so that it gets integrated and we can
get rid of it at the next upstream release.

Thanks a lot!

This was the missing part, thanks for the tip...
