crossgcc/Makefile: Allow making toolchains using multiple cores

I looked for a way to pass the 'make crossgcc -j8' on to buildgcc, but
    didn't find a way to get that value directly.  MAKEFLAGS turns -j8 into
    a jobserver variable.

Instead, this patch allows the number of CPUs to be set on the command
    line through a variable instead.

Example: 'make crossgcc BUILDJOBS=8'
