And it didn't :{

Both debian-ppc64 and fedora-ppc64le failed (UNRESOLVED) 
gdb.base/break-idempotent.exp under both native-gdbserver and native-
extended-gdbserver
https://builder.sourceware.org/buildbot/#builders/76/builds/446
https://builder.sourceware.org/buildbot/#builders/85/builds/294

So I have removed that one too from the list.
The CI test list now looks like:

# Only a small subset of tests that are fast and known to PASS.
gdb_test_exp = ("TESTS= "
                "gdb.base/break-always.exp "
                "gdb.base/break-caller-line.exp "
                "gdb.base/break-entry.exp "
                "gdb.base/break.exp "
                "gdb.base/break-fun-addr.exp "
                "gdb.base/break-include.exp "
                "gdb.base/break-inline.exp "
                "gdb.base/break-main-file-remove-fail.exp "
                "gdb.base/break-on-linker-gcd-function.exp "
                "gdb.base/breakpoint-in-ro-region.exp "
                "gdb.base/breakpoint-shadow.exp "
                "gdb.base/break-probes.exp "
                "gdb.gdb/unittest.exp "
                "gdb.server/unittest.exp ")

Which will be run three times with make gdb-check, once without a
target_board, once with native-gdbserver and once with native-extended-
gdbserver on centos-x86_64, fedora-x86_64, debian-armhf, debian-arm64,
fedora-s390x, debian-ppc64, fedora-ppc64le, opensusetw-x86_64,
opensuseleap-x86_64 (debian-armhf only does a build, no make gdb-check
because of https://sourceware.org/bugzilla/show_bug.cgi?id=28561)
I'll add a debian-i386 builder so there is more 32bit coverage.

All are green now (with the latest change to remove break-idempotent)
https://builder.sourceware.org/buildbot/#/builders?tags=gdb

Question is if this is a good list, does it need more tests? And should
it maybe be maintained in the binutils-gdb repo instead of in the
builder repo?

For example we could have a make check-gdb-ci target which does what
the buildbot would do (and then the buildbot could just call that).

Cheers,

Mark
