An assertion in the test fails on a number of targets due to
a missing strlen optimization. I plan to add the optimization
for GCC 9 but it's too late to add it now. To prevent the
failure r258896 disables and xfails the assertion for targets
other than x86. Attached is the change for reference.
I tested the change with a native x86_64-linux compiler and
with a powerpc64le-linux cross-compiler.
