Do these test cases need to be updated?

They shouldn't need to be. The util/testsuite_random.h header was changed to
catch the new exception type that should be thrown from the library. If they're
failing it implies the library wasn't rebuilt so is still throwing the old
exception type. Odd.

Those tests pass for me with a native powerpc64le-unknown-linux-gnu compiler on
gcc112.

It failed on just the one power 8 system where it fails every time.

configure --enable-languages=c,fortran,c++ --enable-secureplt --with-cpu=power8
--disable-bootstrap --disable-multilib

I will experiment a bit.

Could the testsuite be finding an older libstdc++.so somewhere in the
LD_LIBRARY_PATH?

make  -k check

This is from powerpc64le-unknown-linux-gnu/libstdc++-v3/testsuite/libstdc++.log

I assume the LD_LIBRARY_PATH there is the one used and nothing in it appears
out of order.

BTW, I tried various changes in configure options, build compilers, binutils,
and such in case something there was an issue but it always fails on just this
one power 8 system.  It works fine on another similar power 8 and other power X
(X!=8) systems.
