And on many platforms (well, at least a few years ago) a "shared"
library doesn't have to be PIC. The dynamic loader can do relocation
when it loads the file. (Then it can't be shared.)
But this was a few years ago on Solaris and BSDs, it could be
different now.

On most platforms the code in a *.a library is not shared library code, e.g.
it is not PIC or something like that. Nevertheless, I think that the *.o
files GHCi loads are not exactly shared libraries, they are incrementally
linked relocatable object code (correct me if I'm wrong here, the details of
shared libraries are still a kind of black art...). So you might have luck
with unpacking and re-linking like that:
ar x libblah.a
ld -r -x -o /my/new/blah.o *.o
The linker flags for doing this vary, depending on the platform, you can have
a look at GHC's autoconf magic for hints if it doesn't work like mentioned
above.
Cheers,
S.
