Remove DOS/DJGPP support

DJGPP is a port of the GNU toolchain to 32-bit x86 systems running DOS.
The last known attempt to build Perl on it was on 5.20, which only got
as far as building miniperl.

- * <rich@phekda.freeserve.co.uk>: The DJGPP port has code that converts
- * the return code of system() into the form that Unixy wait usually
- * returns:
- *
- * - signal number in bits 0-6;
- * - core dump flag in bit 7;
- * - exit code in bits 8-15.
- *
- * Bits 0-7 are always zero for DJGPP, because it uses system().
- * See djgpp.c.
- *
- * POSIX::W* use the W* macros from <sys/wait.h> to decode
- * the return code. Unfortunately the W* macros for DJGPP use
- * a different format than Unixy wait does. So there's a mismatch
- * and, say, WEXITSTATUS($?) will return bogus values.
- *
- * So here we add hack to redefine the W* macros from DJGPP's <sys/wait.h>
- * to work with our return-code conversion.
