Really fix make for paralell building WebKitGTK+

[Armin]

Hello. Finally, at the last two attempts I've found a patch that will let WebKitGTK version 1.9.92 (latest development version which will be part of GNOME 3.6) build cleanly when building it with make -jn where n is number of CPU-s.

Patch is available in the repository as make-3.82-upstream_fixes-3.patch

It is in fact -2 with patch referenced in this bug: ​https://bugzilla.redhat.com/show_bug.cgi?id=835424 that points to upstream cvs.

~/src/webkit-1.9.92$ time ( ./configure --prefix=/usr --libexecdir=/usr/lib/WebKit --enable-introspection && ~/make/make -j4 )

make[1]: Leaving directory `/home/armin/src/webkit-1.9.92'

real	79m20.275s
user	147m1.183s

~/make/make is actually newly patched make for testing.
