Comment (by jeremyhu@…):

 From IRC, it turns out each platform has a separate index, so that should
 work out fine.

 Unfortunately, this doesn't quite work because the system sees `[ldelete
 $all_llvm_variants $variantname]` as a single variant.  Eg:

 {{{
 Warning: Variant llvm38 conflicts with non-existing variant llvm39 llvmdev
 }}}

 r152081 addresses the main issue (note that the accidental change to
 wiggle was reverted in the following commit), but I'd prefer to generate
 the variants instead of listing them all out if that's possible.  Leaving
 this open to track taking the spirit of the rest of the change.
