sure, though there's no need at all (except for the .struct part) to do
the testing on Solaris. I believe there are ready-made Solaris/x86
VirtualBox images, though. For the multilib problem, you can easily
configure gcc for i686-pc-linux-gnu with --enable-targets=all on a
Linux/x86_64 box (with a few necessary 32-bit development packages
added), so the default multilib is non-x86_64, while the x86_64 multilib
is only used with -m64.
I gave your patch a quick whirl on i386-pc-solaris2.12 (with /bin/as),
and just that multilib problem is still unfixed. For the (default)
32-bit multilib, the test is skipped as should be, but for the 64-bit
multilib, compilations still lack the required -m64, so they fail with

as before. To check how things were otherwise, I just manually
assembled/compiled do-test.S and ms-sysv.c with -m64, linked them into
ms-sysv.exe, which ran successfully, so it seems were getting closer.
However, I still don't understand why you are jumping through all these
hoops in ms-sysv.exp doing the compilations etc. manually rather than
just relying on dg-runtest or similar. This would avoid all this
multilib trouble nicely, and massivly reduce ms-sysv.exp.
One or two nits about PR management, btw.: it is good practice to take
the PR if you're working on it. And just add the URL to the patch
submissing into the URL field.
Thanks.
