Compiling GNU Radio from source on an embedded board takes much longer
than using a cross compiler. Also, during the compile on a low memory
embedded board, parts of the com[ile takes lots of memory and you may
need to nurse the build during this part of the build.

My i7 builds gnuradio loads faster than even a quad A15.

Both approaches work, I just do not like to wait :)
