On second thought, the above was not the best idea, since changing the
value of a variable cannot affect the path immediately, at least not
easily.

So I have now added a new function, 'startup-redirect-eln-cache',
which can be called in your init files to change the user-specific
part of 'native-comp-eln-load-path'.  For best results, call that
function in your early-init file.

Please see if the latest master branch solves the issue you reported,
if you use that function instead of setting
'native-comp-eln-load-path' directly.
