[OE-core] [PATCH 1/1] ghostscript: resolve the gconfig.h conflict

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

Both base/lib.mak and psi/int.mak will create file gconfig.h:
    lib.mak: $(CP_) $(gconfig_h) $(GLGEN)gconfig.h
    int.mak: $(CP_) $(gconfig_h) $(PSGEN)gconfig.h

If $(GLGEN) is same with $(PSGEN), the $(GLGEN)gconfig.h will be
overridden by $(PSGEN)gconfig.h in a parallel build, and this
maybe cause build errors.

Upstream has fixed this issue, just portback its fixes from:
    http://downloads.ghostscript.com/public/ghostscript-9.06.tar.gz
