    Makefile: Check $CC variable returned from xcompile is not empty.
    
    If xcompile can't find out suitable GCC compiler for i386/armv7, it
    will not set $CC_i386/$CC_armv7 variable. Makefile sets $CC variable
    from xcompile, and will print strange error messages when executing
    $CC program if $CC is empty.
    
    Add checking to avoid this problem. If $CC is empty, also delete
    invalid .xcompile file, so Make can recreate this file next time.
