pthread.m4: Add missing 'test' to conditional
Commit
c5def62d (autoconf: update pthread checks) accidentally omitted
a 'test' in one of the conditionals. This causes an ugly error message
during configure:
checking for pthread_attr_init in -lpthread... yes
./configure[31043]: x-lpthread: not found [No such file or directory]
Replace the missing 'test'.
