[PATCH 5/7] newlib: libc: install CRT0 straight out of subdir

[Mike Frysinger]

There's no need to have a sys/ subdir just to copy the sys/$arch/crt0.o
up to sys/crt0.o, and then have libc/ copy sys/crt0.o up again.  Just
have libc/ refer to sys/$arch/crt0.o directly and drop the intermediate
makefile entirely.
