I did look at it a bit, and here's what's needs to be done:
  
  - bfd (binutils): Need to be able to specify a shared flag for sections.
    That part is somewhat easy.
  - gas (binutils): Need to be able parse section flags containing shared
    flag. Also easy.
  - gcc: Somehow we need to be able to tell the compiler about this "shared"
    link. MSVC does it with a linker comment, but GCC doesn't have such
    a facility directly. It's going to take a bit of work. I might add
    an __attribute__((shared)), but haven't thought of the other
    possibilities yet.

The current binutils release simply won't work -- the CVS/development tree
has some fixes that are absolutely needed for this to even start working.
However, my quick test is somehow creating bad executable, so more work
needs to be done.

This is Anders' baby. Since he's on the list, we're safe.
