Implement compiled-in library search paths: any `-L' argument encountered

while `dynamic link-mode' is on, is recorded in the executable. The
run-time linker will search these paths after $LD_LIBRARY_PATH but
before the default set and those currently in the hints file.
The feature is disabled whenever for set[ug]id programs.

"weak symbol" support (fudged into `a.out' by means of the n_other field).

Weak symbols are to replace indirect (type N_INDR) symbols and will help
to clean up name spaces in libraries.
Also, some misc. bug fixes, including PR 586, and use stdio for the output
file entirely.

Careful when claiming jump slots in the "force alias" case.
...
Taking the address of a function must not cause it to be relocated to
a possibly already allocated jump slot. C++ virtual function tables are
an example of this.

`ld -r -x' now supported on all object files.
Support for long archive member names (AR_EFMT1 format),
thanks to Bill Sommerfeld/Mark Eichin
Do the right(?) thing with symbol aliases (N_INDR) for POSIX lover, especially
when equiping shared libraries with these (this was *not* fun).
Handle silly archives (.sa) for people who needs them; turn on by `-Bsilly'.
