Looks like it breaks a couple of tests by causing the comparison of the expected packet to not match?

@ChrisDodd: I'm getting a lot of failures with the current master using make check-bmv2:

============================================================================
Testsuite summary for p4c 16

# TOTAL: 180
# PASS:  125

# ERROR: 0

Thoughts?

@ChrisDodd, turns out that the python code handles spaces very well. The only issue that I found is the one I sent you email about with the undefined symbol for bm_runtime::standard::BmMtActProfGroup.

And then this fixes the mac version which can't seem to handle glob.glob ... go figure. With this fix, running on the mac, i get the following results:
