Worked for me on 10.10.5

Indeed it will not work before 10.8 because the load command in this
binary (which decides where the entry point is) is of type LC_MAIN
which appeared in 10.8 instead of the older LC_UNIXTHREAD.

Note also that this binary includes a LC_VERSION_MIN_MACOSX load
command which says the minimum version is 10.9. You should probably
add -mmacosx-version-min=10.8 to your gcc options, even when
compiling under 10.9.
