util/xcompile: Look for the host compiler in XGCCPATH, too (and first)
If there's a host compiler in XGCCPATH, it's likely the same
relatively-current version we use for coreboot, and it's a well-known
quantity, so let's prefer that over alternatives by default.
In addition, look for the C++ host compiler as well.
