commit: http://git.buildroot.net/buildroot/commit/?id=de62a1ab616cf5ecc674ce5205d34e9f8c383cf8
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The host-libxml2 package does not depend on zlib or lzma, but may
detect versions available on the host. This can cause problems in the
following situation:

 1 host-libxml2 is built, finds an available lzma library in the
   system, enables lzma support by using it.

 2 host-xz is built, which installs a different version of the lzma
   library into $(HOST_DIR)

 3 host-libxslt is built, tries to link against libxml2, which fails
   because now the visible lzma library is the one from
   $(HOST_DIR)/usr/lib and no longer the one libxml2 was built agains.

To fix this, this patch passes --without-zlib and --without-lzma to
the host package.

In addition, since the target variant of libxml2 does not have
provisions to depend on the target lzma, we also pass --without-lzma
for the target variant. The case of zlib for the target was already
properly taken into account.

Fixes:
