Log Message:
GCC 4.7's gfortran on SunOS generates verbose output which includes spaces
in-between "-l" and the library name.  This confuses libtool which parses
the compiler output, and results in trying to pass arguments such as
"-l-lgfortran" and failing.

In addition there are multiple BUILDLINK_DIR references, but only the first
is stripped, resulting in "-L-L/path".

Fix both these issues and bump PKGREVISION of libtool-fortran.
