gettext_0.19.%.bbappend: Fix/enable shared building of gettext

Fix building of shared gettext for i686/32-bit mingw32. This adds a
patch which fixes an issue with gnulib that is included in gettext.

This patch does not need to be submitted upstream as it is fixing an
issue with the included version of gnulib. Upstream gnulib has already
fixed this issue and upstream gettext has already updated the included
gnulib, however gettext has not yet made a release that includes this
fix.
