Not the git sources. Does the attached patch help ? If it is ok I will 
push it.

Use as:

    --with-rtems-bspopts="options list"

Note, --without-rtems-tests is supported by the RSB.

Excellent. It is really nice to see this happening.

Subject: [PATCH] rtems: Add support for users to supply BSP options for
 configure.

The user can provide --with-rtems-bspopts and these are added
to the RTEMS configure command line.
