[Buildroot] [PATCH] gettext: add dependency on host-libxml2 for host-gettext.

[Nicolas Cavallari]

From: Ignacy Gawędzki <ignacy.gawedzki at green-communications.fr>

Otherwise, the locally-installed libxml2 will be used, which may
depend on a locally-installed liblzma which may create conflict
if host-liblzma is compiled.
