Changes to all build scripts:
* all remaining occurences of 'make -j N' replaced by
'make -j $(nproc)'
* obsolete 'atom' machine architecture replaced with
'bonnell', but both new and old MARCH strings are kept
for compatibility
* optimize TMP variable setting
* add OUTDIR variable (default to $TMP) that defines output
directory for package; the goal is to simplify building
in containers
