Thomas Petazzoni 60e5ed19e7 gdb: disable on Blackfin
gdbserver does not build on Blackfin FLAT (undefined reference to
`_td_thr_tlsbase') and while it builds on Blackfin FDPIC, it's pretty
unlikely that it is going to work properly with the cross-gdb provided
by the Analog Devices toolchain: the Analog Devices toolchain provides
a 6.6 cross-gdb, while we use gdb 7.8.2 for gdbserver.

Therefore, let's simply disable gdb completely for Blackfin.

Fixes:

GDB, the GNU Project debugger, allows you to see what is
going on `inside' another program while it executes -- or
what another program was doing at the moment it crashed.
This option allows to build gdbserver and/or the gdb
debugger for the target.
For embedded development, the most common solution is to
build only 'gdbserver' for the target, and use a cross-gdb
on the host. See BR2_PACKAGE_HOST_GDB in the Toolchain menu
to enable one. Notice that external toolchains often provide
their own pre-built cross-gdb and gdbserver binaries.
