gettext: Switch to disabling nls and reducing -native build dependencies to a set of pre built m4 macros

When analysing our build performance, its apparent that binutils-cross
takes an age to get built. This is due to its dependencies on
flex-native and bison-native which in turn depend on gettext-native.

gettext-native is problematic as it has a significant dependency chain
of its own and takes an age to build. What is worse is that we never
care about the native language support in -native and -cross packages
since we always force the C locale.

This patch therefore disables nls for all -native packages (its already
disabled for -cross) and adds a new gettext-minimal-native package which
contains the m4 macros to keep autoconf/automake happy.

This means we gain a significant build time speedup by the removal of
gettext-native from most dependency chains (only being part of gettext
for the target now).

For now the LICENCE field says GPLv3, the macros are actually under a
FSF MIT like licence so we need to update this part of the patch in due
course.
