I believe that will require to part ways from the reproducer that was attached
to BZ#29459.
I wouldn't be surprised if we ended up with a test that is close
to stdio-common/tst-fwrite-pipe.c , i.e. use pipes instead of a
piped stdout.

Another option is to completely remove stdio-common/tst-fwrite-bz29459
relying only on stdio-common/tst-fwrite-pipe.
