Minor patch to AM_GTK_WITH_NLS in GTK+ 1.2.7

[gtk-devel-list thewrittenword com]

AM_GTK_WITH_NLS doesn't work quite right on Solaris. Output to configure
looks like:
checking whether NLS is requested... yes
checking for libintl.h... yes
checking for dgettext in libc... no
checking for bindtextdomain in -lintl... yes
checking for dgettext in libintl... checking for dgettext in -lintl...
yes
yes
checking for msgfmt... /bin/msgfmt

The following patch fixes this.
