Log:
Cope with old linuxes use of /lib/tls hack for an optional thread-local-storage
version of libc/libpthread. The launch scripts add /lib/tls:/usr/lib/tls: to
LD_LIBRARY_PATH instead of /lib:/usr/lib: if the VM is linked to /lib/tls/libc.
Property changes on: branches/Cog/platforms/Cross/vm/sqSCCSVersion.h
