fix linking error for shared libs when using ifc

Hi Chris,

Thanks for the report. Looks like libtool is needed to link the shared libs
in case of ifc (similar to your earlier report for blas-reference bug #112390).

The attached patch fixes this for me, please give it a spin. Thanks!

Markus, 
 
Many thanks - the patch has fixed all compilation problems for lapack-reference too. 
It compiled with ifc and installed OK. 
 
Thanks 
Chris 

Hi Chris, 
 
Thanks a lot for testing. The patch was applied to the lapack-reference-3.0-r2.ebuild 
in CVS.
