What causes libtool to relink?

[Christian Weisgerber]

I'm completely stuck on a problem report that comes down to this:
"/bin/sh ../../libtool --mode=install" for a loadable module triggers
libtool to attempt to relink the .la file on the reporter's system,
which eventually fails.  I cannot reproduce this.  No such relinking
happens here, libtool simply installs the .so file.

What causes libtool to "relink" a .la file?
