Steps to reproduce the behavior

./configure
make

I think we should just not build debugger then for the unsupported platforms. It should not prevent radare2 from building.

P.S.: See also https://github.com/radareorg/ideas/issues/227

use --without-debugger. but adding basic debugger support should be easy with a shell
