gettext: use included libxml and libcroco

[YOCTO #1400]

By using the included libxml and libcroco, we do not create additional
on this core library. There was an ordering issue that when one library
was not built, but gettext detected the other library a compliation would
fail, this will force it to always use the included libraries.
