The sizes of items represented in s-oscons.ads can (and do) change

At present, s-oscons.ads is only built once (in gcc/ada) and sym-

This is causing a bunch of failures on i686-darwin9 where the m64
multi-lib has generally larger structures than the m32 native.
On m64 targets with m32 multi-libs, this tends to be hidden by the
fact that (generally) the m32 entities are smaller than their m64
counterparts. However, it's still wrong (at least insofar as
wasting memory - if not on any more serious scale).
The attached patch moves the generation and use of the xoscons tool
to the the library makefile (as suggested by Thomas) and adjusts the
libada/Makefile dependency to point to this tool. The remaining
dependencies should (AFAICT) be handled by the gnatlib target -
which thence depends on the required objects.
I don't have that many targets to test - and would very much welcome
any more-Ada-build-system-aware eyes cast over this.
This DTRT on i686-darwin9 (no unexpected fails at m64 when it's
applied).
