This should be `memcmp (...) == 0`.  Currently, the function returns true when
the frame is not an outer frame id, which is the opposite of what it is supposed
to do.

With this, the test gdb.base/break.exp on AArch64 runs fine.  I will launch a full
test run to see if there are any other problems.

You can make the new function return "bool" instead of "int", and use true/false instead
of zero/non-zero (both in the code and comments).
