a build from scratch revealed few more issues with this patch too.

1. We have to only remove gettext from dependencies if its a target
package for all other it still it needed otherwise all native and
cross tools start failing to build
 e.g. binutils-cross this can be easily solved by a patch

second problem is that EXTRA_OECONF when recipes override it instead
of += or appending etc.
then --enable|--disable-nls that we added via gettext_oeconf() is lost
as a result some packages complain about config.rpath
when USE_NLS is set to no the reason is their configure is missing the
argument --disable-nls this works ok
for eglibc based targets since default is to enable-nls if nothing is
specified but uclibc fails. As a testcase try to preprocess
utils-linux
recipe and check the contents of EXTRA_OECONF
