add proper build options (helps for building a package)

[epsilon-0]

• add option for cpu optimizations
• add option for sys/std.h
• remove aml as subdirectory and make proper dependency

This helps in packaging to gentoo as CPU specific optimizations will not work on all ARM/x86_64 platforms.

@any1 I've updated and simplified the PR with only the option for systemtap.

Could you check and see if it can be merged now?
