As someone who often switches between mostly-compatible machines
(qemux86/qemux86-64/genericx86/nuc) I'm often hitting problems like
this.  Most recently libproxy was using a sysroot that didn't exist,
which prompted my cmake patch.

Presumably the change would replace the package-architecture element
in the path with the machine name.  Seems reasonable to me: a more
logical layout of files without any meaningful impact to performance.
