I don't see how that helps?  Nativeness is not the most important
factor here.  In fact, it's not even particularly important; a MIPS64
GDB doesn't have to care which ABI it was compiled for or which
architecture the debuggee was compiled for (well, except for
thread_db).

No, --with-sysroot should be honored no matter what the target is.  It
should definitely be honored for core.  It should be honored for
native, too - you can be debugging in a chroot relative to GDB.

Since no one has ever come up with such a design, I'm keeping my hopes
in check...
