Still there in GDB 5.2.1

Andris thanks for the GDB 5.2.1 link. I had to remove the check for the
${srcdir}/gdb/testsuite/gdb.cxx as there was no testsuite directory in the
zip.

configure fails as follows on P4:-

checking for stdlib.h... (cached) yes
*** BFD does not support target i786-pc-msdosdjgpp.
*** Look in bfd/config.bfd for supported targets.
Configure in c:/dj204/gnu/gdb-5.2_1/opcodes failed, exiting.

The quick fix for this is as follows:
1) Add the following line above the main $srcdir/configure line:-
    target=i586-pc-msdosdjgpp
2) Add a $target parameter to the $srcdir/configure line:-
   $srcdir/configure  $target --srcdir="$srcdir" --prefix='${DJDIR}' \
                              ^^^^^^ NEW

This forces the build to be for a i586. This seems to be the default for
most of the packages. I could have used i686.

Once I performed the 3 changes (remove testsuite check, add target line, add
configure $target line) I build GDB 5.2.1 without a problem.
