However, if we revert the backout of crt1.c, then we know that all
shared executables will work the moment we fix rtld and libpthread.
If we keep the call to _init_tls() removed from crt1.c then every
binary linked on a 5.3 machine needs to be relinked the moment we
do add proper TLS support. So, to minimize (future) burden I suggest
we change crt1.c back for 5.3 as well. Otherwise this will just be
another exception on Alpha...

The above obviously conditional upon re@ approval.
