DRIVER_SELF_SPECS and multilib

[gnubie gnubie <gcc dot gnubie at gmail dot com>]

Hi,

I notice that if you add a DRIVER_SELF_SPEC option and then add that
option as a MULTILIB_OPTION, it doesn't build certain libraries for
that multilib variant.

for example, if you add:

"%{mtestoption:-mcpu=cortex-a5 %<mtestoption}"

(and then define mtestoption in the opt file)

then add mtestoption as a multilib variant, it builds some of the
libraries for that variant but not others.  notable missing libraries
being:

libstdc++, libssp and libsupc++.

most of the others are there.  If you just add cortex-a5 as the
variant then it works fine.

Is this by design?

Thanks,
Carlos
