MozJS build error, when building Servo on Mac

[gterzian]

On Mac OS 10.11.6, I can currently only successfully build Servo when manually rewinding MozJS to this commit servo/mozjs@cdf21f7 in Cargo.lock.

If I leave things unchanged, I get configure: error: Building ICU requires either yasm or a GNU assembler. If you do not have either of those available for this platform you must use --without-intl-api

Which might relate to this commit servo/mozjs@78037f9 @emilio

Also worth noting, is that when I try to build using this commit (I tried because it's the one just before the one mentioned above)servo/mozjs@590a672, I get
ld: symbol(s) not found for architecture x86_64 @nox

You need to install yasm, it was added to the dependency requirements.

ok, thanks! @emilio

Closing this then, thanks for the report! :)

Oh, for the record, the PR that updated mozjs and added the yasm dependency is #13836
