Subject: [configure] Fixup breakage with recent autoconf

To avoid these warnings:
configure.in:29: error: possibly undefined macro: LT_CURRENT
      If this token and others are legitimate, please use
m4_pattern_allow.
      See the Autoconf documentation.
configure.in:33: error: possibly undefined macro: LT_REVISION
configure.in:38: error: possibly undefined macro: LT_AGE

we simply use an m4_define for those variables instead.
