RROR: no fileid for debian-ppc64-builder
UNRESOLVED: gdb.base/break-idempotent.exp: pie=nopie:
always_inserted=off: watch: gdb_breakpoint: set breakpoint at main
(timeout)

I've looked briefly at the logs.  I recall one of those tests having a
FAIL with one of the test permutations, but not an UNRESOLVED.  We'll
need to poke further.

has_hw_wp_support: Default, hardware watchpoint
not deteced

I see a typo in there somewhere... :-)
