[Bug preprocessor/34211] New: Wrong preprocessor called in build-i686-cygwin/libiberty/configure

["eha at doredevelopment dot dk" <gcc-bugzilla at gcc dot gnu dot org>]

When configure is called in the build-i686-cygwin/libiberty subdir, CC is set
correctly to build gcc, but CPP is inherited as "powerpc-linux-gcc -E".

It seems like we should be setting CPP to "${CC_FOR_BUILD} -E" in all the
places where CC is set to ${CC_FOR_BUILD}.
