I need the -static for qemu and simple remote execution (copy binary via scp,
execute via ssh). And yes, -static makes it much easier to avoid the
LD_LIBRARY_PATH issue.
I'll make -static optional, and default to -static-libgcc -static-libstdc++.
The latter should still work for most remote execution setups (works for me,
at least).

At this point the simd testsuite is very close to being usable for other
Parallelism TS 2 implementations. That's a feature I'd support if there's
interest outside of libstdc++.

Ah, but good point. I have comments in simd_math.h (i.e. the other patch)
like: "Fold @p x into [-¼π, ¼π] and [...]". These comments are not in the
testsuite. I guess I need to replace all non-ASCII chars there?
Attached is the diff to the previous patch. In addition to the -static change
I added license headers (as noted on IRC) and I improved the Makefile
generator: Instead of only passing TESTFLAGS and GCC_TEST_SIMULATOR as
environment variables, place the initial values into the generated Makefile.
This makes it much easier to work on tests or fixes for failures.
I'll top-post the squashed simd patches.
