libgcc2.h patch breaks c4x target

[Michael Hayes]

The following patch breaks complilation of libgcc2.c for the C4x
target.  Can you please explain what exactly the problem was
that required this patch so that we can come up with a compromise.

Thanks, Michael.

	* libgcc2.h: Use LONG_LONG_TYPE_SIZE instead of MIN_UNITS_PER_WORD
	to decide whether 64-bit support must be generated.
