It seems the real problem is a misunderstanding regarding the semantics
of EMBEDDED.
EMBEDDED is _not_ strictly connected to any usage of the kernel.
All EMBEDDED does is to offer additional option for people needing a
small kernel in space-limited environments.
CC_OPTIMIZE_FOR_SIZE is one example, but it also allows to e.g. deselect
futex support.
(ISA || EISA || PCI || EMBEDDED) doesn't make any sense since this
dependency expresses the supported busses. If this was required for any
purpose, it should be reported to find a proper solution.

Even further, I don't see any reason for using -O - the resulting code
is expected to be both bigger and slower than with -Os.
Is this a workaround for a gcc bug on some platform?
