[bug #57242] Non-recursive command passes invalid jobserver file descriptors

[Martin Liška]

Follow-up Comment #14, bug #57242 (project make):

> One note: an ideal implementation would look for the _last_ instance of
--jobserver-auth in MAKEFLAGS, not the first instance.  In the current code in
Git, if we are using anonymous pipes and we invoke a sub-process which is not
considered to be a recursive make, we will add an extra
"--jobserver-auth=-2,-2" to the END of MAKEFLAGS to disable the jobserver
(unfortunately it's complicated to try to replace the existing option so
instead we just add an overriding option.
> 
> This should make the jobserver more reliable than before, even when using
anonymous pipes.  It doesn't solve all problems though: named pipes works
better in many situations.

Yeah, I've done that in v2:
