fix: Expand system-dependent -m{arch,cpu,tune}=native options

The -march=native, -mcpu=native and -mtune=native options have different
effects depending on which system the compiler is run.

Fix this by asking the compiler which cc1 options the -m*=native options
expand to and including them in the input hash.

Fixes #824.
