Can you explain this more please?

vendor/onigmo/Makefile.am patch which is removed in this pull request is force to update Makefile.am.
So, this update causes to be force to execute regenerate configure.
I've added just make instead.
This is because, Groonga-4.0.8's Makefile has trivial bug.

When just execute make install, it causes that libtool cannot find library libonig.la like this:

==> Patching
patching file lib/ii.c
patching file lib/grn.h
==> ./configure --prefix=/usr/local/Cellar/groonga/4.0.8 --with-zlib --disable-zeromq --with-mruby --without-libstemmer
==> make install
libtool: link: cannot find the library `../vendor/onigmo-source/libonig.la' or unhandled argument `../vendor/onigmo-source/libonig.la'
make[3]: *** [libgroonga.la] Error 1
make[2]: *** [install-recursive] Error 1
make[1]: *** [install] Error 2
make: *** [install-recursive] Error 1

But this error can avoid just add system "make" before system "make install"

system "autoreconf", "--force", "--install" is too exaggerated to fix problem.

I hope this answer your question.
