Follow-up Comment #1, bug #49844 (project make):
Hello.
There is a bug in your trivial example:
1) 'seq 1000 | xargs -n1000 make -j5'
expands to
'make -j5 1 2 3 4 5 6 7 ...'
and
2) 'seq 1000 | xargs -n1000 make -j'
expands to
'make -j 1 2 3 4 5 6 7 ...'
As we can see, in second example '1' after '-j' make interprets as number of
jobs, so "it not do any parallelization at all".
