Stop i386/djgpp-stdint.h being unused

[Joseph S. Myers]

I noted in <http://gcc.gnu.org/ml/gcc-patches/2011-02/msg01254.html>
that, of the unused gcc/config/ headers, i386/djgpp-stdint.h was most
appropriately dealt with by making the relevant configuration use it
instead of removing the header.  This patch does so.  (The issue of
this header being unused was previously noted in
<http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00964.html>.)

Tested building cc1 and xgcc for cross to i686-pc-msdosdjgpp.  OK to
commit?

	* config.gcc (i[34567]86-pc-msdosdjgpp*): Use i386/djgpp-stdint.h.
