   The tests in gdb.base/solib_threshold.exp are completely useless on
   anything but hppa-hpux.  It should probably be moved to gdb.hp.

I'd prefer to just take your patch, thanks.  The concept is applicable
to all targets (including remotes), although it's unclear if anybody
other than HP will ever have the energy to implement user-settable
limits on the quantity of solib symbols loaded.  Note that HP sets
their default limit to 100 MB(!), which says something about the
size of executables that their customers are using GDB on...
