This helps in defining LE tunes and at the same time specifies endianness on compiler cmdline clearly, clang e.g. defaults to little-endian always, so unless specified with -mbig-endian won't compile the code right (From OE-Core rev: e0fd699d398f0e88fb208970dea7b74e6e9431fe) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
