[Bug fortran/37634] New: Fix libgfortran compiling to support GCC_NO_EXECUTABLES

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

See: http://gcc.gnu.org/ml/fortran/2008-09/msg00380.html
and following emails.

The configure script does link tests which cause some kinds of cross
compilations to fail.

Solution (cf. email thread, see above link):
a) Approved patch in the link above
b) Remove "AC_LIBTOOL_DLOPEN" which does not seem to be used
c) Add an if-block around the AC_CHECK_FUNCS
d) Check what else is needed, e.g. AC_CHECK_LIB
