Add Android options from specs to linux-android.opt

[Joseph S. Myers]

In preparation for the driver only accepting options listed in .opt
files, and not other options that simply happen to match some spec,
this patch adds Android options matched by specs in linux-android.h to
linux-android.opt.

Tested building cc1 and xgcc for cross to arm-linux-androideabi.  OK
to commit?  (While there are no maintainers listed for Linux or
Android targets in general, I'm not sure I should thereby consider
them unmaintained targets and so consider cleanups to them
preapproved.)
