[PATCH] net: wan: wanxl: define CROSS_COMPILE_M68K

It was used but never set.  The hardcoded value from before the dawn of
time was non-standard; the usual name for cross-tools is $TRIPLET-$TOOL

 This is neither the host nor target arch, thus it's very unlikely to be
 set by the user.  With this patch, it works out of the box on Debian
 and Fedora.
