* Makefile.in (LIB2FUNCS): Remove _varargs and __dummy.
* libgcc-std.ver: Remove __builtin_saveregs, __dummy, and __empty.
* libgcc2.c: Remove __dummy and __builtin_saveregs.
* libgcc2.h: Don't prototype __builtin_saveregs or __dummy.
* config/i860/varargs.asm: New file - preserve i860 __builtin_saveregs
for future reference.
