=begin
 $ rm -rf .ext/rdoc
 $ make rdoc
 $ ls -d .ext/rdoc/Queue
 ls: cannot access .ext/rdoc/Queue: No such file or directory

When "ext/thread/thread.c" is specified as rdoc command option, it works.

 $ ./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- \
     --disable-gems "./bin/rdoc" --root "." --page-dir "./doc" --encoding=UTF-8 \
     --no-force-update --all --ri --op ".ext/rdoc" --debug ext/thread/thread.c
 $ ls -d .ext/rdoc/Queue
 .ext/rdoc/Queue
=end
