unfortunately causes them to compile with -O0... this results in a python
binary that is excruciatingly slow and makes the entire test suite run take
a long time.

The main problem is that doing so would disable test_gdb. Humans don't run
gdb on those binaries, but the test suite does.
I agree it would be nice to figure out a way to run most of the tests on an
optimised build, though.
