If the pthread.h header is found, make sure library containing
"pthread_atfork" is added to the list of libraries against which to
link. On some hosts (e.g. openSUSE 15.1) "-lpthread" needs to be
explicitly added in order for the code to compile correctly.
We already had a workaround for this for native builds, but using some
external toolchains, we can be bit by this for the target recipe as
well.
Most of this is courtesy Trevor Woerner <twoerner@gmail.com>, via his
patch at stevegrubb/libcap-ng#10, the last thanks to Khem Raj.
