* Makefile.in: Introduce MAINLIBS.
* configure.in: Link libc_r against the ruby executable on
FreeBSD, which is the first attempt to work around a certain
problem regarding pthread on FreeBSD. It should make ruby/libruby
happy when it loads an extention to a library compiled and linked
with -pthread. Note, however, that libruby is _not_ linked with
libc_r so as not to mess up pthread unfriendly stuff including
apache+mod_ruby and vim6+ruby_interp.
