[Buildroot] [PATCH 2/2] gdb: disable on AArch64

[Thomas Petazzoni]

The mainline gdb does not yet have AArch64 support at all, so let's
disable it for this platform. The external toolchain provided by
Linaro has gdbserver + cross-gdb, so it already provides what's
necessary to do some debugging.

Fixes
