Thanks.  The resulting command line is a over half of the noted maximum
detected on your system.  Since the detection adds a safety margin, for
this package you can probably get away simply by editing the generated
libtool script after running configure and increasing max_cmd_len a bit,
say doubling it.

Does that ld support @-files (a command line argument of @FILE should
cause it to read additional arguments from FILE) or --whole-archive?
We'd need some way that is less buggy to shove more objects into a
shared library, in order to deploy a better workaround in libtool.  Or,
preferably, somebody should fix your ld to support -r, or get the newer
ld to work ...

Cheers,
Ralf
