Minimum RAM for "libbsd"? Can't run in 8MB on "imxrt".

By "RTEMS work space" I mean the space between bsp_section_work_begin and bsp_section_work_end, which I assume is handed over to the unified work space.  I also assume allocated "libbsd" data structures come from there.

After reducing the space for the mbufs I still run out of RAM.  I've been patching rtems_bsd_allocator_domain_page_mbuf_size in the debugger for test.  I'll put it in at compile time but looking at the code that won't make a difference.
