[chromium] Don't use goma to preprocess bindings idl files

I'm cool with this, just wondering about weird build environments (a la Chrome OS chroot, though that one looks ok, or Android, that I don't know about), but maybe we already depend on /usr/bin/gcc for something else.

Ah, I didn't think about Android.  Let's see what the EWS bot thinks.

Over email, Nico asks:

> Doesn't it make more sense to let goma fall back to local if it sees a -E parameter? That's what I proposed to the goma folks. (Also, in clang builds, the script should probably use clang?)

Making goma smarter sounds great to me.

I don't think it matters much whether we use clang or gcc for preprocessing idl files.  For example, the Qt port uses moc.

Before-collision text:

I think a nicer fix is to let goma fall back to local if it sees -E transparently.

On OS X, /usr/bin/gcc will eventually disappear. Is it possible to set this to the clang binary if clang==1 is set?

Yeah, we should rollout after a goma fix is pushed.

Sure.

nit: This is redundant, clang is always set for OS=="mac". Probably want this for OS="ios" too.

This uses the system clang instead of "our" clang, but for preprocessing I suppose that's cool.

Please see bug 108089.

In my environment OSX 10.6.8 environment, the hard-coding of the /usr/bin/clang path from this bug causes the build step that preprocesses the bindings idl files to generate hundreds of "clang: warning: not using the clang compiler for C++ inputs" messages.
