[PATCH:macros] XORG_PROG_RAWCPP: Use AC_PATH_TOOL to find preprocessor

[Alan Coopersmith]

From: Marvin Schmidt <marv at exherbo.org>

On some distributions tools like cpp are prefixed with the host-triple,
to check for this prefixed version first AC_PATH_TOOL should be used. If
no prefixed cpp, it will fallback to the unprefixed name.

This looks reasonable to me and seems to work in my normal builds.
But I have zero experience with cross-compiling and no way to test
that, so I'm sending out to give those with more experience there a
chance to pipe in before pushing.
