[Buildroot] [PATCH v2] wget: fix host-gettext build dependency race

[Baruch Siach]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

Currently, the gettextization of wget works by chance:
  - host-gettext is added as a dependency to wget;
  - gettextize is run as a post-patch hook.

But the dependencies are only guaranteed to be built and installed
for the configure step, not the patch step. Because post-patch hooks
are part of the patch step, we have no guarantee that the dependency
to host-gettext is done by the time we gettextize wget.

This happens to work by chance, since wget sorts alphabetically after
gettext, so we indeed have host-gettext built and installed by the
time we need to gettextize wget.

This is prone to fail in the parallel build case, since we can no
longer rely on alphabetical order in that case.

Instead, run gettextize in PRE_CONFIGURE_HOOK to avoid the race.

This should be _HOOKS. Will fix shortly.
