icu does not recognize 'uclinux' as a supported platform. While making it recognize uclinux is easy, there is another problem down the road: icu does very weird things to generate an ELF library containing static data (libicudata.a), and the generated library being ELF, it is not compatible with the FLAT binary format expected by uclinux platforms such as Blackfin in FLAT format. Therefore, we simply disallow the selection of icu on FLAT platforms. Note that adding a dependency on BR2_BINFMT_ELF doesn't work, because BR2_BINFMT_FDPIC is considered to be separate (even if technically FDPIC is a derivative of ELF). That's why the dependency we're adding is "depends on !BR2_BINFMT_FLAT" and not "depends on BR2_BINFMT_ELF".
