With newer glibc versions, pthread was merged into the main library so there is no longer any need to link with -lpthread. On newer systems this means that linker flag is dropped from places like pkgconfig .pc files. If uninative then uses this newer library on an older system, the flag is missing and linker errors about missing symbols occur.
Adding the linkage unconditionally to our uninative linking flags avoids that problem at a potential cost of slight over linking.
