--- Comment #9 from Arsen Arsenović <arsen at gcc dot gnu.org> ---
removing EXTRA_HOST_FLAGS from the gettext targets fixed the build on my
cfarm112.

overall, I'm not sure overriding what subconfigures discover and adjust CC and
CFLAGS with is a good idea.  it seems sensible to allow subpackages to have
that disabled (or to require packages to enable that functionality, but that
change would be more intrusive)
