mach build-cef could not compile embedding

[cb88]

I imagine this may just be a temporary problem but I can build servo itself but not ./mach build-cef.

This is on Gentoo amd64 I don't imagine that matters much as servo uses a snapshot of rust and not my natively installed version as far as I am aware.

 ./mach env

CEF build completed in 5.75s

[jdm]

Huh, we stopped building CEF on our build machines at some point recently apparently.

[jdm]

No, that's not true:
http://build.servo.org/builders/linux2/builds/2873/steps/compile_1/logs/stdio is from the most recent automated build.

[jdm]

We just stopped recognizing failed builds for it :/

[jdm]

Same for android builds, which explains why @connorimes was seeing a build error recently.

[cb88]

Ah well good thing I had a go at it manually and reported it then! I was hoping you did have automated builds for CEF... I was thinking of updating an FLTK CEF demo I found.

[cb88]

I was able to build-cef. So looks like that is fixed although I'm not sure about the buildbot reporting failures...

[Ms2ger]

Yes, sorry, forgot to update this issue. I fixed the build in #7359, and buildbot should report failures now (except for android, which I didn't know how to fix)
