Also... an important couple of features:

TLS works on certain hardware (e.g. with hardware supported tls, like
armv7a), but not on all architectures, like in GNU [1], [2]. It's
probably better to blanket-disable this for now via a portage profile
variable.

SMP does not currently work OOTB. There are some patches floating
around[3], with issues that mainly lie outside of bionic, but I the
'official' SMP code will be available whenever Honeycomb is
released[4] ... which is of course whenever Google decides to do
release Honeycomb.
