configure: For Windows builds, add the CROSS_PREFIX to $RC and $STRIP.

zlib's original win32/Makefile.gcc did the same, but this was removed in
7d17132436431d5f62cf5089623073d72d07deb0. It is kind of essential for
cross-compiling a Win32 build on Linux, since `windres` most certainly
doesn't exist, and the regular `strip` may not be able to handle DLLs.

It should probably actually be something like

	RC="${RC-${CROSS_PREFIX}windres}"

and

	STRIP="${STRIP-${CROSS_PREFIX}strip}"

to be consistent with the assignments of $AR, $RANLIB and $NM, but this
didn't work for some reason.
