I considered such an approach, but what happens if you a prefix that 
doesn't yet exist on the system?  AFAICS you would have the library in 
$my_new_prefix/lib and the DLL in /bin, which doesn't seem quite right.

Shared libraries should be, and generally are, in or under $prefix/lib. 
  The only way I see my patch not helping is if the library is in or 
under $libexecdir AND --libexecdir is set to something other than 
$prefix/lib (like the GNU default $prefix/libexec).  But IMHO that would 
be a problem with the package in question.

But how would you make a patch in a form that would be accepted upstream?

I have three cases where non-module libtool libraries are installed into 
a subdir of $prefix/lib:

* evolution: libraries under $libdir/evolution/$MAJOR.$MINOR

* mysql: libraries under $libdir/mysql

* libffi-3.0: usually under $prefix/lib, but I move the library under 
$prefix/lib/libffi/lib so that it's not grabbed accidentally instead of 
gcc's libffi (just like the headers are by default under 
$prefix/lib/libffi/include).
