LU-19053 build: allow specifying "make rpms" build dir

Currently "make rpms" will create a temporary directory with mktemp
to hold the intermediate build products, and this ends up in /tmp.
This can cause issues if /tmp is not large enough for the full build.

Allow specifying "BUILDDIR=DIR" to redirect the intermediate build
products into the specified directory. This allows you to run:

    BUILDDIR=/var/tmp make rpms

or

    BUILDDIR=/var/tmp make debs
