[ruby-talk:04254] patch: path trimming in configure

Configure handles path literally at least for --prefix and appends it's
relative path as '/include', not plain 'include'.

Thus I thought to say --prefix=/home/my_home/test_bed, but then I though
about root dir and decided the path should be /home/my_home/test_bed/ so
that root is specified as --prefix=/. Trailing '/' causes ruby to -I
(nclude) and install to /home/my_home/test_bed//bin. This causes no problems
(dunno why unix allows this), but seems quite ackward, so I made following
patch which removes trailing slash from prefix option.

Same kind of thing should probably be applied to all path options, but I
haven't used them, so I thought I should not mess up.
