[PATCH HEAD]: newer autoconf macros in Libtool

[Ralf Wildenhues]

This patch removes two more warnings from `autoconf -Wobsolete' when
used on Libtool CVS HEAD.  The remaining two (PUSH_LANG) need further
Automake support for Java.

Regards,
Ralf

        * m4/libtool.m4 (_LT_ENABLE_LOCK), m4/ltdl.m4 (LT_LIB_DLLOAD):
        Replace AC_TRY_LINK with AC_LINK_IFELSE to get rid of `autoconf
        -Wobsolete' warnings.
