    Mk/Features/lto.mk: Add checks for powerpc64 and riscv64
    
    Add checks for powerpc64 and riscv64 since they won't work with LTO.
    
    This is a bit crude on powerpc64 but can be improved upon later.
    LTO does work on this platform using GCC but will fail using lld.
    
    This commit also introduces LTO_DISABLE_CHECK which can be used to
    override.
