[patch] add stpcpy, mempcpy and fix strcpy

I was trying to build binutils and it couldn't find stpcpy or mempcpy so I
added them.
I also noticed that the entry for __builtin_strcpy referenced strcmpt , which
seemed wrong,
so I fixed that.
binutils will compile with this patch as long as Werror is disabled.

Thanks - I added the changes, but slightly differently

static TWORD mempcpyt[] = { VOID|PTR, VOID|PTR, SIZET, INT };

did not add this (same as memcpyt)

static TWORD stpcpyt[] = { CHAR|PTR, CHAR|PTR, INT };

nor this (same as strcpyt)

{ "__builtin___mempcpy_chk", builtin_unimp, 4, mempcpyt, VOID|PTR },

{ "__builtin_mempcpy", builtin_unimp, 3, mempcpyt, VOID|PTR },

added these (using memcpyt)

< { "__builtin_strcpy", builtin_unimp, 2, strcmpt, CHAR|PTR },

{ "__builtin_strcpy", builtin_unimp, 2, strcpyt, CHAR|PTR },

fixed that (it would have worked fine, but as you say.. bit strange :)

{ "__builtin_stpcpy", builtin_unimp, 2, stpcpyt, CHAR|PTR },

and added (using strcpyt)
