I noticed that the last "maint info breakpoints" test expects the
output to contain:
.*hw watchpoint.*
But some platforms do not have hw watchpoints (for instance, the
sim on erc32 doesn't). So I changed the expected output to accept
either.
gdb/testsuite/ChangeLog:
* gdb.python/py-breakpoint.exp: Fix the expected output of
one of the "maint info breakpoints" tests to accept the output
generated on platforms that do not have hardware watchpoints.
