My understanding, looking at the git history and other comments, is that
this tool is meant to be build for Windows/Linux/Mac OSes. And
apparently Windows only supports to build statically.

You can see that someone removed that line for the 'APPLE' build, so
I've offered a pull-request to NXP to only do so for WIN32 instead [1].

However, while writing that PR, I linked to this thread archive and
realized Joerg is already offering a patch for mfgtools [2].

Adding Joerg to this thread then, I'll let you guys know if the PR is
accepted. @Joerg, let me know if you want to do the next patch version,
no need to do the same work twice ;)

BTW, I saw that you made a change for the git commit version, I'd
suggest sending a PR for that too instead of patching it in Buildroot.

Regards,
Gary
