Re: [PATCH v1 1/1] configure: correct tooldir install path

Hi Neal,

It looks like this got missed during the holiday season.

When you patch configure.ac, you need to regenerate configure (not directly
edit it).  You can either run autoconf or autoreconf which will need
autoconf 2.69 installed on your system.  When you submit a patch, you don't
submit the generated files such as configure, but you will need to
regenerate it to test your changes locally.  Thus, your patch should have
the changes needed to configure.ac but not configure   The configure file
will get regenerated for the repo by whoever reviews, approves, and merges
the patch.
