This works, but is afaik less efficient for the static lib case.

The real fix is imho to build the object files twice, like how libtool
does it.

If you look at the Debian package, they work around it by adding a
seperate .c -> .sho build rule, which adds -fPIC, and then link the .so
file with the .sho files instead.
