DJGPP fix: remove both conftest and conftest.exe.

The DJGPP compiler may create both `a.out' and `a.exe' without -o,
and both `conftest' and `conftest.exe' with `-o conftest', but not
with `-o conftest.exe'.

* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
`conftest' without $ac_exeext suffix.

        DJGPP fix: do not try to source /dev/null as cache or site file.
        * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
        load the cache or site file if it is `/dev/null', as DJGPP treats
