No, there's one more criterion: And those special actions make the library
unsuitable for use in programs not compiled to use threads.
For example, on Debian *all* libraries are compiled with -D_REENTANT -fPIC.
Anything else would be a major headache for the distribution.
It causes a 3-5% performance drop on i386 and much less on other
architectures. However then all libraries are suitable for use in both
threaded and non-threaded applications.
There may still be some architectures out there where two versions are needed.
But I'm not aware of any.
