[svn-r17440] Purpose:

    Add warning to configure

Description:

   Patched up the configure script to issue a warning when the user
   has supplied the --enable-static-exec flag on a system that libtool
   indicates does not support the -static linker flag.

Tested:

   jam, smirom, linew, liberty.
