x11/gtk2+extra not happy with gmake 3.82

[Erik Bertelsen <bertelsen.erik%gmail.com@localhost>]

When building gtk2+extra with pkgsrc update as of today, I see:


===> Building for gtk2+extra-2.1.2nb1
/usr/pkg/bin/gmake  all-recursive
gmake[1]: Entering directory

spaces?).  Stop.
gmake[2]: Leaving directory

`/home/NetBSD/wrkobj/x11/gtk2+extra/work.i386/gtk+extra-2.1.2'
gmake: *** [all] Error 2
*** Error code 2

My suspicion is that this package's Makefile violates some new
stricter requirements of gmake 3.82.

Not being an expert on pkgsrc build patches, I'm sorry to not provide a fix.
