Thanks.  The problem you encountered is actually a regression in 3.6.0.
I've fixed it here:

 Ninja: Do not force response files when no sysconf(3) limit is used
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=86dd2427

and queued the change for merge to `release` for 3.6.1.

I've also applied your change on `master` for development toward 3.7:

 Ninja: Generalize check for sysconf(3) call
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=5ec17e61

Thanks,
