1258785 - "checking yasm version... Traceback" after "checking for yasm... not found"

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Nick Alexander :nalexander [he/him]]

margaret reports problems building Fennec on Mac OS X, with --enable-artifact-builds.  In this configuration, yasm should not be required, so we probably shouldn't even check for it.  However, if it's not found, we *definitely* shouldn't version check.

Log snippet:

Oh, apparently the code I wrote doesn't work:
https://hg.mozilla.org/integration/mozilla-inbound/annotate/d5efe76a40b3/moz.configure#l131

because of:
https://dxr.mozilla.org/mozilla-central/rev/4037eb98974db1b1e0b5012c8a7f3a36428eaa11/build/moz.configure/checks.configure#68

check_prog will return 'not found' for missing programs, which is obviously not a falsy value! I wonder if we could just use `None` instead?
