Hi,

I found a bug in the fTPM build that it has a bug if more than 16 cores
are available. On a machine with 20 cors the my build faild constantly.
Limit hardcoded the ftpm build to -j 16 fixed the issue.

Is there a correct ISAR way to limit $(PARALLEL_MAKE) to max 16?

Or do I have to write me an own if (nproc > 16) -j 16 variable?

Thanks

Sven

Hello.

Just export it before the build:
```
export PARALLEL_MAKE="-j 10"
```

It should work both with build using kas-container and ordinary build.

Hi

sure that would work, but I wanted to just limit for that one recipe
and not for the complete build.

So it can be included directly into the recipe and be used by others.

Hello

```
PARALLEL_MAKE = "-j 10"
```

Adding this to the recipe also works.
