in a .6 file, an export line
//ffi T localfib remotefib remote.so
means the dynamic linker should initialize
localfib, always a pointer, to the address of
remotefib, either text (T) or data (D) after
loading remote.so.
the C compiler will generate an export section
when given the pragmas
#pragma package fib
#pragma ffi T localfib remotefib remote.so
needing #pragma package is a bit of a kludge
and hopefully could go away later.
this is just the 6 tool chain support.
other architectures will happen once 6 settles down.
code using this to do FFI is in a later CL.

and make 5c, 8c use them.
centralizes reachability analysis
and switch generation.
now 8c doesn't have spurious warnings
in pkg/runtime.

This makes it easy to build with other flags
(like -ggdb) or other compilers (like cc64).

these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.
(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)
the longs were rare enough that i don't think
it will cause integration problems.
