The bug is in Mk/bsd.ruby.mk.  It is bogusly clearing CONFIGURE_TARGET.
At least for passing the --target GNU tuple to GNU autoconf.  GNU
software has always used a 3-TUPPLE: cpu, vender, OS.  While <cpu>-<os>
might be the proper tuple for Ruby itself, it isn't for GNU autoconf.
Modern versions of GNU autoconf are a lot more strict about demanding a
3-tuple vs. 2-tuple than older versions.

Setting RUBY_ARCH?=${ARCH}-portbld-freebsd${OSREL:C/\..*//}${RUBY_R} gets
GNU autoconf to configure properly. The "-pc-" in "x86_64-pc-freebsd5" is
a big warning GNU configure isn't being run correctly.
