qoriq: new target Add a new target named "qoriq", that will support boards using PowerPC processors from NXP's QorIQ brand. This doesn't actually add support for any board yet, so that installation instructions can go in the commit message of the commit that adds actual support for a board. Using CONFIG_E6500_CPU here due to the kernel using -mcpu=powerpc64 rather than -mcpu=e5500 when selecting CONFIG_E5500_CPU. The only difference between e5500 and e6500 is AltiVec support, and the kernel checks for it at runtime. Musl will only check at runtime if AltiVec support is disabled at compile-time, so we need to use e5500 in CPU_TYPE to avoid SIGILL. Math emulation (CONFIG_MATH_EMULATION_HW_UNIMPLEMENTED) is required, as neither e5500 nor e6500 implement fsqrt nor fsqrts, and musl hardcodes sqrt and sqrtf to use these ASM instructions on PowerPC64.

qoriq: use KERNEL_SUFFIX in Build/sdcard-img Use the KERNEL_SUFFIX variable in Build/sdcard-img, rather than using hardcoded "-kernel.bin", to allow overriding KERNEL_SUFFIX for a device.
