cc-cross-prefix is used to check if there exists a $(CC) in path with
one of the listed prefixes. The first prefix where there exist a
prefix$(CC) in the PATH is returned - and if no prefix$(CC) is found
then nothing is returned.
Additional prefixes are separated by a single space in the
call of cc-cross-prefix.

This functionality is useful for architecture Makefiles that try
to set CROSS_COMPILE to well-known values but may have several
values to select between.
It is recommended only to try to set CROSS_COMPILE is it is a cross
build (host arch is different from target arch). And is CROSS_COMPILE
It is recommended only to try to set CROSS_COMPILE if it is a cross
build (host arch is different from target arch). And if CROSS_COMPILE
is already set then leave it with the old value.
