Just to clarify a bit more for who did not follow that bug: what we did
there was not precisely what Joost asked for (i.e. build libasmrun.a
with -fPIC). Rather the patch offers two different libraries:
libcamlrun.a (no -fPIC) and libcamlrun_shared.so (-fPIC). The reason was
a performance penalty in using the -fPIC version.

Both in Debian and Fedora package you now have both libraries.

That said, I share Rich's suggestion: please file a bug (with patch
would be even better :)), that enable building 2 different versions of
libcamlrun, one built with -fPIC, the other as it is now.
