r44257 の変更以後 Mac OS X で make enc が以下のような失敗をすることがあるようです。

making enc
linking encoding encdb.bundle
ld: warning: -pie being ignored. It is only used when linking a main executable

make: *** [enc] Error 2

r44257 では configure の --opt-dir を処理する位置を移動しているのですが、この中に LDFLAGS と DLDFLAGS にフラグを追加する処理があります。
しかしこの結果 $target_os で分岐して darwin の時 DLDFLAGS を設定しているところの前にこの処理がきてしまったため DLDFLAGS に -Wl,-undefined,dynamic_lookup -Wl,-multiply_defined,suppress が追加されなくなったのが直接の原因ではないかと思います。

• Status changed from Assigned to Closed
• % Done changed from 0 to 100

This issue was solved with changeset r44297.
Tomoyuki, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

configure.in: use RUBY_APPEND_OPTIONS

• configure.in: DLDFLAGS is defined in --with-opt-dir handler, so
  ${DLDFLAGS=} does not work now. use RUBY_APPEND_OPTIONS instead.
