This failure is because of spaces in your pathname. It might be simpler
to run in a different directory rather than fix all the problems this
causes in the test suite.

This test, as it says, is testing if notmuch was compiled with debugging
symbols.  Rather than yet another special case for mac, I'd be curious
if there is a portable test for this (perhaps using nm?). In any case,
this one test failing should not be fatal.

At a guess, this again has to do with spaces in the pathname. Maybe this
is fixable with more quoting, but it's really independent of mac vs
gnu/linux. In this instance it looks like quoting "test_results_path"
would help.
