1. (I think) the string you need is "multilib_os_dir" not "multilib_dir" (b=
ut
ICBW about that .. there are many twisty passages in the determination of t=
hese
things).

2. The concern remains that the language spec handler is run pretty much fi=
rst
in the stack and there are several other claims on the command line that co=
uld
have specs that alter (or add) flags to the command line, giving a different
outcome to the computation of mulilib_{,os_}dir.

perhaps it would be a good idea to post this and ask the opinion of someone
like Joseph on the direction.=
