Unfortunately it is not neutral to 2.13:

+case $testdir in
+  d10v-elf) subdirs="d10v-elf"
+ ;;
+  d30v-elf) subdirs="d10v-elf d30v-elf"
+ ;;
+  fr30-elf) subdirs="d10v-elf d30v-elf fr30-elf"
+ ;;
+  m32r-elf) subdirs="d10v-elf d30v-elf fr30-elf m32r-elf"
+ ;;
+  mips64el-elf) subdirs="d10v-elf d30v-elf fr30-elf m32r-elf mips64el-elf"
+ ;;
+  *) ;;
+esac

It does seem to work as expected for 2.5x, unsurprisingly.

We've already got a mix of required autoconf versions for GDB, since
libiberty switched over last year.  So I don't see a good reason to
stay with 2.13 if someone's gone and done all the necessary work to
upgrade us...

There were two autoconf patches in the list of patches for src/ you
sent me in April.  Are they necessary?  If so, would you ping the
autoconf maintainers about them again, please?  Then we'd need to wait
for 2.60.

If no one sees a reason to wait, and the autoconf patches are not
necessary, I'll update the gdb directory to 2.5x and apply this patch
in a few days.  I'll do sim also if you'll send me the remaining
changes you needed.
