package/gdb: prevent gdbserver being selected for RISC-V builds

Browse Source 
There is currently no version of gdbserver for RISC-V. Until this
is implemented we will prevent both the direct and indirect
selection of gdbserver for RISC-V builds. In practice this means
that 'cross gdb for the host' cannot be selected and that
'full debugger' must be automatically selected for the gdb target
package.

Build the gdbserver stub to run on the target.
A full gdb is needed to debug the progam.
