Erratum: LDFLAGS is different, since Ubuntu adds -Wl,-Bsymbolic-
functions.

I think this has been like that for quite some time, so it seems
unlikely to be the source of the problem, but a test could be to
recompile openblas on Ubuntu with DEB_LDFLAGS_MAINT_STRIP="-Wl,-
Bsymbolic-functions" in the environment.
