I don't think you should be adding this.
Please, see the commit 464c79207c89f247f97b344495924eabb0c9738e
(punt unused clean/distclean targets) by Mike.

You should be using the new standard for specifying the machine type.
Please, read the README file (CONFIG_MACH_TYPE option).

2 sets of parenthesis is enough.
I don't see any good in having the whole expression wrapped.

same here

This one looks good, I think the previous should be the same.

I think the common way would be to define a "weak" implementation in

I think, adding a comment to which #if that #else belongs,
will improve the understanding/readability.
