No problem. It actually currently keeps us from installing sparc64 since
systemd is no longer up-to-date.

Further research shows that it might actually be a glibc bug which
occurred first with glibc_2.21. The problem never occurred with
glibc_2.19.

The last successful build of the systemd package was with glibc_2.19:

After that, we used 2.21 and xsltproc started segfaulting.

It's also unlikely to be a problem with execessive stack usage as
manipulating the stack size with ulimit does not have any influence
until the stack size is intentionally set to very small values.

Still debugging.
