1395047 - --enable-tests for MinGW build is broken because it thinks it's linux

Status: RESOLVED FIXED

> WARNING - TEST-UNEXPECTED-FAIL | /home/worker/workspace/build/src/testing/xpcshell/selftest.py | XPCShellTestsTests.testAddTaskRunNextTest, line 1049: No module named fix_linux_stack

I traced this to http://searchfox.org/mozilla-central/source/testing/mozbase/mozrunner/mozrunner/utils.py#284 where it thinks we are Linux, because well we sure look like Linux I bet!

The problem is, I'm not quite sure where in mozinfo we set isLinux, and even if I corrected it, I'm not sure we could run tests successfully in the current way we run tests!

We set it here:

http://searchfox.org/mozilla-central/source/testing/mozbase/mozinfo/mozinfo/mozinfo.py#255

or thereabouts.  At least that selftest check probably needs to be updated to consider the *target* machine we're running on, rather than the host...and there are probably many other instances besides, since 'isLinux' probably worked OK for the other major cross-compilation case of Android on Linux.

n.b.: we don't (and have never) run `make check` on any of our cross-compiled builds, for this and other reasons.

You should be able to drop this, --enable-tests is the default.

Thanks, fixed.  Will land this once I get Bug 1406736 sorted (which is breaking the -tests build).
