Add target-independent specs options to .opt files

[Joseph S. Myers]

This patch adds target-independent options that were previously known
only in specs to .opt files.

Most of these are linker options.  In addition, there's the -Q option;
-Qn (-fno-ident), -Qy (which appears to be intended as the opposite of
-Qn so is made available as such target-independently); the Ada driver
-k8 option; and the Java -static-libgcj option (handled only in the
generated libgcj.spec).

I'm not sure what the linker -Z option handled by gcc.c is for; GNU ld
doesn't appear to have such an option.  It's quite possible it should
be target-specific, but right now the specs pass it to the linker on
all targets.

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