Patches for libtool support on NAG Fortran compiler for Darwin OS

[Jürgen Reuter]

Dear libtool team (cc to Peter)
as discussed with Peter I send to you a diff (compared to the 
2.4 official version of libtool) to support the NAG Fortran compiler
on Darwin 64bit machines.

The two changes are (also attached as diff patches):
-- in the file libtool.m4:

sowie in ltmain.sh (as I explained in my email to Peter the nagfor 
uses gcc as a linker which then uses ld. This demands a double wrapping
through -Wl,-Wl flags)
