Description: Link gnatcoll with pthread to circumvent #760211.
 On armel armhf hurd-i386 kfreebsd-amd64 s390x, inlining of
 Ada.Task_Attributes creates a direct dependency to the
 pthread_getspecific symbol.
 With --as-needed, -lpthread has no other effect than fixing the link
 stage for buggy architectures.
