libtool 1.4 -- totally insane resource usage

[Morten Welinder]

Hi there,

linking gnumeric using libtool 1.4 currently takes an unreasonable
time.  It's more or less all spent in libtool, see the report below
(which does not include subprocesses).  To reproduce, just run
your favourite libtool link under strace.

libtool has outgrown being a shell script.  Due to style and lack
of caching, it hits the same files over and over again.  Hundreds
of times, in fact.

Moreover, being a shell script, it starts an absurd number of
subprocesses -- 1013 to be precise.

FYI, this is on a Solaris 2.8/Sparc system.  All file systems, but
/tmp, are NFS.
