--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
So, what presumably happens (can't tell because the interesting part of the
log, the bit leading to the error is not included) is that:
- skip_hw_watchpoint_tests returns 0 meaning hw watchpoints are supported
- gdb fails to set a hw watchpoint and instead sets a sw watchpoint

That particular situation is handled for arm:
...
    -re "Watchpoint (\[0-9\]+): .*\r\n$gdb_prompt $" {
        if {[istarget "arm*-*-*"]} {
            untested $test
            set wpnum 0
        }
    }
...
but not for any other target so wpnum remains "" and we run into the error
here:
...
if {$wpnum} {
...

Possibly this has been fixed for powerpc by commit 8d4e4d13afb ("gdb Power 9
add test for HW watchpoint support."), but not for any other targets.
