Add root_dir option to reltool.config
When generating a node using rebar generate, rebar always used
code:root_dir() to find the Erlang installation to clone into the node
tree. However, for anyone wishing to build a cross-compiled node, there
was no way to override this. This patch adds a new option to
reltool.config file to allow an alternate root_dir to be specified, for
example:
{root_dir, "/tmp/otp_R14B03_armv7l"}
This assumes that the contents of /tmp/otp_R14B03_armv7l has been
generated using the instructions found in the xcomp directory in your
$ERL_TOP structure. NOTE: you may have to add additional filters to
exclude files not present in the xcomp version, such as the .smp files
if you have disabled that.
