Well it's unfortunate it's exporting those at all. And I'm not sure
how those are supposed to be used, so depending on that it might make
more sense to add __FreeBSD_kernel__ to the existing __FreeBSD__
stanza. Otherwise maybe add a new "OS=GNU/KFREEBSD" for example, as
glibc is not an actual OS.

In any case this might produce warnings on non GNU/kFreeBSD systems if
a system header is included before <jam.h> as OSMINOR will be defined
twice.
