safe-ctype.h (HC_UNKNOWN, [...]): New #defines. 

include:
	* safe-ctype.h (HC_UNKNOWN, HC_ASCII, HC_EBCDIC, HOST_CHARSET):
	New #defines.
libiberty:
	* safe-ctype.c: Separate out EOF==-1 check.  Use HOST_CHARSET
	for charset determination.
gcc:
	* aclocal.m4 (gcc_AC_C_CHARSET): Delete.
	* configure.in: Don't use gcc_AC_C_CHARSET.
	* configure, config.in: Regenerate.
	* config/i370/i370.c, config/i370/i370.h: Use
	(HOST_CHARSET == HC_EBCDIC) or (HOST_CHARSET == HC_ASCII)
	instead of HOST_EBCDIC or !HOST_EBCDIC.  Clarify comments a tad.
