Add fontconfig bug fix for parallel build

Hi,

fontconfig is affected by a compile bug that only occurs from time to time when parallel compilation is enabled. The bug is described at
https://bugs.freedesktop.org/show_bug.cgi?id=16464.

The attached patch includes the fix for fontconfig in buildroot. However, it modifies a Makefile.am file, so running automake is needed, but I'm not sure Buildroot will do that automatically (as the bug only occurs sometimes, it's quite hard to test whether the fix properly works or not).

Sincerly,

Thomas

Add a parallel compilation fix for fontconfig

This patch adds a patch to fix bug
https://bugs.freedesktop.org/show_bug.cgi?id=16464 affecting parallel compilation of fontconfig.

The patch is the one proposed in the bugzilla entry, available at
https://bugs.freedesktop.org/attachment.cgi?id=17294.

Without this patch, the compilation of fontconfig sometimes fails with:

In file included from fc-case.c:25:
../src/fcint.h:118:21: error: fcalias.h: No such file or directory
