fix page size on aarch64 (#226)
fix page size on aarch64 (#226)

debian/ubuntu use 4k pages while centos uses 64k pages. 64k pages work
on 4k page systems while a 4k compiled binary will throw this error:
ELF load command alignment not page-aligned

This patch attempts to pass a linker flag that should force 64k page
alignment at all times
