Thomas, All,
On 2018-11-23 15:58 +0100, Thomas Petazzoni spake thusly:
> With per-package folder support, top-level parallel build becomes
> safe, so we can enclose the .NOTPARALLEL statement in a
> !BR2_PER_PACKAGE_DIRECTORIES condition.

The biggish comment is now completely wrong. The correct solution is not
to remove the line, but to enable the BR2_PER_PACKAGE_DIRECTORIES option.
