Added last-resort dynamic library names.

LIBNAME_LINK_SPEC=`echo "$library_names_spec" | $SED 's/^.* //'`

DLGUESSLIB=`name=$2 eval echo "$libname_spec"`

DLGUESSFILE=`libname="$DLGUESSLIB" release="" major="" versuffix="" eval echo "$LIBNAME_LINK_SPEC"`

dnl Last resort in case libtool knows nothing about shared libs on this platform

test -z "$DLGUESSFILE" && DLGUESSFILE="$DLGUESSLIB$shared_ext"

dnl Synthesize a likely dynamic library name in case we can't find an actual one

SO_NAME_SPEC="$soname_spec"

dnl soname_spec undefined when identical to the 1st entry in library_names_spec

test -z "$SO_NAME_SPEC" && SO_NAME_SPEC=`echo "$library_names_spec" | $SED 's/ .*$//'`

DLGUESSSOFILE=`libname="$DLGUESSLIB" release="" major="" versuffix="" eval echo "$SO_NAME_SPEC"`

dnl Last resort in case libtool knows nothing about shared libs on this platform

test -z "$DLGUESSSOFILE" && DLGUESSSOFILE="$DLGUESSFILE"

if test "$cross_compiling" = yes; then

  dnl Can't look at filesystem when cross-compiling
