Description

[Daniel Holbert [:dholbert]]

In a Try run that I pushed today with "-p all", I got "B2G L Emulator" builds, which are perma-red due to having an old version of gcc.

My treeherder push:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=0f510321fe1e

Sample failure log:
http://ftp.mozilla.org/pub/mozilla.org/b2g/try-builds/[e-mail]-0f510321fe1e/try-emulator-l/b2g_try_emulator-l_dep-bm76-try1-build0.txt.gz
http://ftp.mozilla.org/pub/mozilla.org/b2g/try-builds/[e-mail]-0f510321fe1e/try-emulator-l-debug/b2g_try_emulator-l-debug_dep-bm76-try1-build1.txt.gz

The logs contain this line:
> INFO -  [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]

...and we end up erroring out with:
{
../../../dist/include/mozilla/Compiler.h:27:6: error: #error "mfbt (and Gecko) require at least gcc 4.6 to build."
}

That bustage is already fixed via a follow-up push to m-c. We're working on another bustage issue right now, though. I'll take care of filing that as needed.
