[Buildroot] [PATCH v2 2/4] toolchain: add bfin support

Fri May 13 12:15:57 UTC 2016
With gcc 6.1.0 and binutils 2.26 internal bfin toolchain
can be used. A gcc patch is required, which was reported upstream.
Signed-off-by: Waldemar Brodkorb <wbx at openadk.org>

v1 -> v2:
- remove conditional patch requested by Thomas Petazzoni
- do not enable BR2_GCC_TARGET_CPU, may be we can use
BR2_TARGET_CPU later for passing -mcpu= via CFLAGS
