[bug #49844] 'make -j' without explicit process count sometimes doesn't parallelize

[Michael Builov]

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".
