gcc: Add gcc configure for PowerPC e500v2/SPE embedded floating point ABI
The e500v2 core utilizes a unique floating point programming model / ABI. We utilize TARGET_FPU = "ppc-efd" to distinguish this choice (Embedded scalar single-precision floating-point). When building the toolchain for this ABI we need configure gcc with --enable-e500_double. (From OE-Core rev: 5136c4ad6279c1593301f6dde9b959ad26a2fd0f) Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
