Subject: Fix initsecondarythread_test runtime failure if GC compiled w/o threads
X-Git-Tag: v8.0.0~1022

Fix initsecondarythread_test runtime failure if GC compiled w/o threads

Now the test should fail during its linking if a single-threaded libgc
is used (this should not happen in case of configure/make).

* tests/initsecondarythread.c (main): Call GC_get_parallel() to ensure
that libgc is compiled with the threads support.
