I agree with Daniel.  I think it's going to be difficult to get the
symtab maintainers to agree to this change.

I'm curious about why it was needed in the first place though.
SOFUN_ADDRESS_MAYBE_MISSING is alread defined for Linux.  Is it
needed for some other (non-Linux) platform?

Hmm...  it just occurred to me that SOFUN_ADDRESS_MAYBE_MISSING needs
to be multiarched.  Once that's done, your problem is solved since
this could be turned on or off at will.
