[Buildroot] [PATCH 2/2] toolchain/gdb: exceptionally allow building gdbserver for the target on blackfin

[Thomas Petazzoni]

In order to guarantee the compatibility between the cross gdb and the
gdbserver, we expect external toolchains to provide both cross gcc and
gdbserver. Unfortunately, external toolchains provided by Analog
Devices for Blackfin do not come with a gdbserver, so we
exceptionnally allow the building on gdbserver even with external
toolchains in the Blackfin case.

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