Short - yes and yes.

Long -
The patch originated with the discovery that i386 version crashed using 
tbb. The addition of arch=i586 to cflags enabled the use of gcc atomics. 
This was merged into the cmake files (src/cmake/platform.cmake) in 1.1.6 
and taken out of the port makefile.

1.1.6 also included the removal of the freebsd condition in thread.h and 
by Larry Gritz's choice it was replaced with a test that left gcc 
atomics off if tbb was turned on. Disabling gcc atomics when tbb is on 
turned out to be a performance hit and 1.1.7 replaced the freebsd 
condition instead of removing the tbb test.

I have submitted an issue for it (instead of a pull request) which seems 
to be the slow way of getting a change. While 1.1.8 appeared to be cli 
tools fixes and 1.1.9 was only docs, I don't want to drop behind so 
updating here with the patch.
