Fix `-Wl,' for Intel Fortran compiler ifort

[Ralf Wildenhues]

Testing revealed that this patch is needed for successful testsuite
results with Intel ifort.  Applied to HEAD and branch-1-5.
(I assume this could break compiler support for version 8 and older; it
is required for version 9.  If somebody has installations to test it
with, please do so, thanks!)

Cheers,
Ralf
