Ow, the fun. Well since the only has_member/function check we do have
right now tests for linux vs. solaris, we should probably be safe. Or at
least know really quickly when we're not safe.

For the android stuff, we'll probably just have one switch for is_android,
for all the things missing in bionic. Very obviously I've done none of the
"how should this work on android" thinking yet :-)
