I think it's better to make this default to cc, not gcc ('cause "gcc" is really
clang on os x, etc). gyp uses cc.

[Nico, 2014/08/13 16:33:07]

Hm, I think clang (!) reads MACOSX_DEPLOYMENT_TARGET from the env, are you sure
this doesn't need to be set at ninja time? Or do the ninja files that cmake
writes convert MACOSX_DEPLOYMENT_TARGET to a -mmacosx-version-min flags? Did you
check the output of `otool -l bin/clang | grep -A 5 LC_VERSION_MIN_MACOSX`?

[hans, 2014/08/13 20:31:02]

Yes, CMake will add -mmacosx-version-min if MACOSX_DEPLOYMENT_TARGET is set.
      cmd LC_VERSION_MIN_MACOSX

  version 10.6
      sdk 10.9

It would if there were any, but we never copy from any source dirs. I double

We already do it for Linux in package.sh. I've added it there for Darwin too.

Most of these flags are the same every time, maybe we can put most of them in a

Yeah :/ When we move this to the .py script one day, I think we should use a
utility function, but for this bash version, I prefer to spell it out, as the
values of many of the referenced variables do change e.g. between the bootstrap
and regular builds.
