1203689 - Use tooltool gcc as host compiler for cross-mac builds

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

The switch to CentOS 6 threw cross-mac builds for a loop, in that the system GCC is 4.4, which our build system rejects as too old. I tried just using the clang we're using as the target compiler but that failed with a `crtbegin.o not found` error (there's another bug on this because ehsan hit it with static analysis builds). I just gave up and used tooltool GCC as the host compiler, this works:

If ehsan gets the clang thing sorted we can probably switch to that and avoid having to download two compilers.

Looks good to me.  If ehsan's got another solution, i'd be happy with that too.

Per bug 1203393 comment 4 you need the gcc package to provide the missing crtbegin.o anyway, so this is really not any worse.
