Well as I see not so easily which is since we share toolchain for architectures and if we let machines add ABI conflicting options then we will be in trouble think of using I could have suggested using something like GLIBC_EXTRA_OECONF but I would not encourage that So one way to go about this is that we use -gnuspe in target triplet which will differentiate SPE targets from classic ppc and then in gcc recipe include files you can do something like EXTRA_OECONF_append_linux-gnuspe = " --enable-e500_double " > >>> * e5500 (64-bit embedded ppc) >> >> this is new I guess.
