Hi,

llvm does this by running config.guess from cmake and reading the result.
But, because it is a cmake package and not a GNU autoconf package
the pkgsrc CONFIG_{GUESS,SUB}_OVERRIDE logic does not kick in.

in the last part of pkgsrc/lang/llvm/Makefile there is a snippet
which manually overrides config.guess with the pkgsrc one which
is supposed to have correct platform detection.

Kind regards,
