This new function will call do_build() twice to produce two builds
and then check their reproducibility.

Changes v3 -> v4:
- Remove spaces on empty lines (suggested by Yann)
Changes v2 -> v3:
- make clean outputs to logfile, similar to other make calls (suggested by y_morin)
- Output dir needs abspath (suggested by y_morin)
- Directly use make clean as arguments rather than putting it into a variable
- Added missing period at end of commit message (suggested by arnout)
Changes v1 -> v2:
- make clean outputs to devnull (suggested by arnout)
- remove unnecessary arguments to make clean (suggested by arnout)
