Does /dev/.mdadm exist?  If it does, try

  make RUN_DIR=/dev/.mdadm

If not, just use

  make CHECK_RUN_DIR=0

You don't need access to the rundir to assemble some devices.

And don't "make install".  Just "make", and then run

 ./mdadm ....

or copy mdadm to some where (e.g. /sbin/mdadm-new) and only use mdadm-new
when you particularly want the new features.
