----------------------------------------
When I tried to compile official github mirror version of ruby on linux system, I get the error:

~~~
$ ./configure
...
checking for broken memmem... no
checking for nroff... /usr/bin/nroff
.ext/include/i686-linux/ruby/config.h updated
ruby library version = 2.2.0
configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating Makefile
config.status: creating ruby-2.2.pc
Downloading Unicode data files...
ruby: Can't chdir to ../enc/unicode/data (fatal)
make: *** [update-unicode] Error 1
~~~

This error happens only in the git version because git don't track emtpy directories ("$(srcdir)/enc/unicode/data").

The following patch may fix this problem.
