That's right.  Libtool has not yet been ported to SkyOS.
Is it similar to Cygwin or some other w32 system?

Depends on whether you want to do the port yourself or want somebody
else to do it for you.  For the former, it's helpful to study the
Libtool documentation, and then dive into libtool.m4 and search for
PORTMEs.  Then add corresponding sections there.  The file may look
a bit (warning -- understatement!) confusing, if you have questions
feel free to ask.

If the latter: we could do such a port, probably.  It will likely take a
little while until I could get to it -- I've a backlog of other stuff.

In any case, providing good, detailed documentation helps a lot.  About
the system, the linker, the runtime loader, library path and library
naming conventions, versioning, inter-library dependency handling, etc.
It helps to copy off of a similar system.

I found this: but that is very terse,
to say the least.

For testing, shell (ssh) access to a system would help enormously.
If that is not possible, someone with some patience and willingness to
run test suites helps, too.  :-)

Show us how.  Is there a way to work around the command line length
limit (if there is one) in the linker, like response files, or linker
