qcc/QCC is some kind of wrapper for GCC, like cc. You can use -Wc,-fPIC but
I think the proper way is to use -shared (which when I tried it passed -fpic
to the compiler). It supports threads but you don't have to specify -pthread
or anything like that.

Do you mean with QCC? You'd have to put -Wc, or -Wl, in front of a lot of
the options to pass them to the compiler and linker.
g++ is available so the gcc toolset sort of works directly and builds some
parts of Boost. The -pthread option isn't supported or needed though so some
libraries refuse to compile with the current gcc.jam. I guess that would be
an easy fix but I don't have much interest in pursuing that at the moment. I
prefer to use the QNX-recommended QCC with the Dinkumware library.
I ran a regression test with the gcc toolset (g++ compiler) by mistake a few
weeks ago when I first started messing around with testing and the results
are on the test summary page for the release branch.
