This sounds more like bug in libxcomp3 (if it uses symbols from libpthread, it must link
to -lpthread [or -pthread]; newer nxproxy likely links to libpthread itself, which hides
this bug; still, this must be fixed in libxcomp3); fwiw, dh_shlibdeps even complained about this:
=== https://buildd.debian.org/status/fetch.php?pkg=nx-libs&arch=amd64&ver=2%3A3.5.99.18-1&stamp=1548946175&raw=0
...
dh_shlibdeps --dpkg-shlibdeps-params=--ignore-missing-info
...
dpkg-shlibdeps: warning: symbol pthread_setspecific used by debian/libxcomp3/usr/lib/x86_64-linux-gnu/libXcomp.so.3.5.99 found in none of the libraries
...
=== cut ===
(this bug seems still present in buster/sid, so I'd suggest filling bug against nx-libs).
