[Autoconf] Add --no-undefined to compiler option
[Autoconf] Add --no-undefined to compiler option

Update the compiler flags to enable the check of undefined function at link time.

It seems the option '-no-undefined' pass in libdleyna_server_1_0_la_LDFLAGS
is not enough. Using libtool, this option should be set to the compiler flags.
