powerpc/85xx: Remove -Wa,-me500
This caused lwsync to be converted to sync on 64-bit (on 32-bit lwsync is generated at runtime, and so wasn't affected). Not using lwsync caused a significant slowdown on certain workloads. Setting this flag for any e500-enabled build is also not friendly to multiplatform kernels. Signed-off-by: Scott Wood <scottwood@freescale.com>
