Support -library=stlport4 with Sun C++ compiler

[Albert Chin]

Sun C++ supports two C++ libraries, -library=Cstd (default), and the
newer -library=stlport4. They are incompatible. Therefore, libtool's
use of -lCstd (equivalent to -library=Cstd) should not be assigned to
$postdeps if -library=stlport4 is in CXXFLAGS. Patch attached.

Patch against branch-1-5 and branch-2.0 attached.

        * libtool.m4 (AC_LIBTOOL_POSTDEP_PREDEP) [ solaris ]:
        Don't set $postdeps to "-lCstd -lCrun" if
        "-library=stlport4" set in CXXFLAGS as stlport4 C++
        library incompatible with Cstd C++ library. Use
        '-library=Cstd -library=Crun' instead of '-lCstd -lCrun'.

        * m4/libtool.m4 (_LT_SYS_HIDDEN_LIBDEPS) [ solaris ]:
        Don't set $postdeps to "-lCstd -lCrun" if
        "-library=stlport4" set in CXXFLAGS as stlport4 C++
        library incompatible with Cstd C++ library. Use
        '-library=Cstd -library=Crun' instead of '-lCstd -lCrun'.
