As of ICU 65.1, upmendex requires -lpthread. Otherwise, it crashes
at sort.c:82, which merely creates the icu_collator:
    icu_collator = ucol_open(icu_locale, &status);

About 10 stack frames deep into the ICU initialization, this winds up calling
(Build/source/libs/icu/icu-src/source/common/umutex.cpp:146):
    std::call_once(*pInitFlag, umtx_init);

which results in a fatal error from stdc++:
    terminate called after throwing an instance of 'std::system_error'
      what():  Unknown error -1

Web searching indicated that that opaque error message is a result of not
linking with -lpthread. So now we do so. So far our other ICU programs
(bibtexu, xetex) don't seem to require it.
