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 options generally accepted by specs for GNU-userspace
targets to a new gnu-user.opt file.  Note that even where these
targets do not use gnu-user.h, the subdirectory specs generally accept
these options, and where the specs do not accept the options that can
reasonably be considered a bug in those specs (except for some uClinux
targets where some of the options may be inapplicable - however, if
the options are inapplicable and not in specs the driver will continue
to reject them as before by the logic for rejecting options not
matched by a spec; that logic is intended to stay, with only the
converse logic of accepting an otherwise unknown option matched by
some spec intended to go).

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.  OK to
commit?
