arch: remove Blackfin architecture
The Blackfin architecture has for a long time been complicated to maintain, with poor support in upstream binutils/gcc. As of April 2018, the Blackfin architecture has been dropped from the upstream Linux kernel. Also, the Analog Device engineer who used to be in touch with the Buildroot community also privately said we should drop the support for this architecture, which Analog Devices is no longer using, promoting and maintaining. The BR2_BINFMT_FLAT_SEP_DATA option becomes unselectable, it will be removed in a future commit. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Reviewed-by: "Yann E.
