>Description:
Canadian cross build of build gdb-6.8 for build=x86_64-linux host=i586-mingw32
target=powerpc-linux, is broken.

It was reported first time back in 14 Jul 2007:
http://sourceware.org/ml/gdb/2007-07/msg00123.html

The problem is that config.h is generated for $(CC), which
for the above mentioned canadian cross is my
586-mingw32-gcc, and included in a number of .c
and .h files i sim/ppc, ending up in both $(CC) and
$(CC_FOR_BUILD) builds.

To fix this, I have added #ifdef HAVE_CONFIG_H in all
places and patched the Makefile.in to define HAVE_CONFIG_H
for all $(CC) build.
