As described in the PR, amd64-pc-solaris2.1[01] Ada bootstrap was failing
for some time. It has turned out that this patch is the culprit:

I couldn't find the gcc-patches posting for this patch, thus I'm missing
the rationale for it. It seems rather counterintuitive and fragile to
me, replacing the canonical $target by the far more varied $target_alias.
If there's really a good reason to keep that patch nonetheless, the
following patch fixes Solaris/x64 bootstrap.
Bootstrapped without regression on amd64-pc-solaris2.10 and
i386-pc-solaris2.11. Ok for mainline?
