bootstrap/3412: -mcoff in CRTSTUFF_T_CFLAGS_S

[Golubev I. N.]

The patch fixes gnats bug 3412.  That is, coff support for sco5 target
was removed by
< http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/i386/sco5.h#rev1.41 >,
but that was not honored in `t-sco5gas'.  The change involved removing
from `t-sco5' code that made difference with `t-sco5gas'.  So now
`t-sco5gas' is not needed at all (should be removed).


Remove COFF support from i?86-*-sco3.2v5*.

* config/i386/t-sco5gas: Removed.

* config.gcc: Likewise.
