Good news, everyone!
I ended up hitting an Internal Compiler Error in flosoft's GCC while
trying to build Firefox with them. After a long and painful saga of
trying to rebuild a newer version of GCC, I eventually discovered the
excellent "toolchain4" cross-compilation project maintained by Ray
Despite using the same base GCC version as flosoft (4.2.1), his compiler
does not hit the ICE with Firefox.
Moreover, with Ray's help, I was able to use his binaries and the
flosoft OSX 10.6 SDK to successfully build a working TBB for Mac from
Gitian. These descriptors are now in the repository, and the Makefile
should now build bundles for all three platforms by default.
There still are some branding and localization bugs, and I have not yet
redone the whole build to verify determinism for MacOS yet, but I am
