849242 - mach build needs to be more informative about Makefile errors

Status: NEW

mach is a little too quiet for me, it makes it really hard to figure out when something is broken. For example:

 0:06.80 Generating LALR tables
 0:12.62 Makefile:60: *** invalid syntax in conditional.  Stop.
 0:12.62 make[4]: *** [export_tier_platform] Error 2
 0:12.62 make[3]: *** [tier_platform] Error 2
 0:12.62 make[2]: *** [default] Error 2
 0:12.62 make[1]: *** [realbuild] Error 2
 0:12.62 make: *** [build] Error 2
 0:12.63 399 compiler warnings present.
Finished building. Built files are in /build/mozilla-central/../debug-mozilla-central

There's an error in a Makefile there, but I cannot figure out which one from this output.

Isn't this a general fault of |make -s|?

Plausibly, yes.

There was also discussion in bug 960458 about the l10n difficulties involved in doing this.
