Well, it is also working around another problem. Somehow, when I
add all the external libraries with 'requirements', the linker
complains about multiple definitions of 'xerbla_' (a frequently
used output routine in Fortran libraries). When adding the ext.
libs with 'usage-requirements', this no longer happens. Dunno
why...

It works! Now, the LAPACK libs are only linked once. Great.
