The strcopy and optimizations are not used when there's no platform data
(espeacially the alignment information).

There are two ways to fix that:
a) an additional parameter to opt or llvm-ld that auto-injects the platform
data or use the native platform
b) a command line tool that outputs the recommendend alignment settings on each
platform to get the best speed

thanks for implementing ;)
