[Buildroot] [PATCH 1/1] package/gutenprint: add back the hook for creating the m4local directory

[Fabrice Fontaine]

Commit 64c42c5e2c26261e26c3548c86b02f55d12f341b removed the hook for
creating the m4local directory with the assumption that it would be
created because the first include is treated in a special way if it
doesn't exists

However, this assumption was wrong as m4local is the second include, the
first one is m4 (which already exists in the archive). So put back the
hook. The other solutions would be to patch:
 - Makefile.{am,in} to remove m4local
 - configure.ac and Makefile.{am,in} to add m4local before m4
However, both solutions don't seem to be upstreamable

Fixes:
