libs passed to ld

[Golubev I. N.]

platform: i386-pc-sco3.2v5.0.2
libtool versions: 1.3.5

`libtool --mode=link' while making shared lib does not pass `-l*'
options from libtool command line to `ld', even if those libraries are
static ones (sco5 allows to use non- PIC in shared libraries).

Static code referenced to by `*.lo' code must be present either in
main program or in shared library itself in order to dynamically link
that library successfully.

Even passing `/usr/lib/libc.so.1 -lc' may be required since there are
two versions of ELF libc: one is shared, and other is static, and
static one contains a superset of stuff in shared one.
