toolchain: kill ADI Blackfin toolchain
This toolchain has many problems which are fixed in contemporary gcc and uClibc-ng. In addition, several hacks are needed to be able to work with this toolchain. All these hacks are removed as well. Also the package exceptions for this toolchain are removed. The BR2_BFIN_INSTALL_FDPIC_SHARED and BR2_BFIN_INSTALL_FLAT_SHARED options don't get a legacy entry. For the ADI toolchain, there already is a legacy entry, so it doesn't make sense to add it twice. For other external toolchains, these options didn't actually work, because they rely on the specific layout of the ADI toolchain.
