If you build WebKit/chromium on Linux (i.e. Chromium/Linux and
Chromium/Android), you're now using ninja. The Chromium Linux Release
and Chromium Android Release build bots seem to be working fine.

Admire the exciting build output:
http://build.webkit.org/builders/Chromium%20Linux%20Release/builds/65467/steps/compile-webkit/logs/stdio

Let us know if anything is not working for you.

(If you must use make, you can pass --no-ninja to update-webkit, and
build-webkit will use make again. If you do this, please let me know
why.)
