type correctness tweek

[Richard Henderson <rth@cygnus.com>]

Gas won't build with the metrowerks compiler, because we passed
an unsigned char* to strcpy, which expects char*.

I took this opportunity to not do two passes across the string.

	* symbols.c (symbol_find_base): Use memcpy instead of strcpy.
	Don't copy before downcaseing.
