how about this one

     function resolvers.platform(t,k)
         local architecture = os.getenv("HOSTTYPE") or resultof("uname 
-m") or ""
         local platform     = os.getenv("MTX_PLATFORM")
         local musl         = find(os.selfdir or "","linuxmusl")
         if platform ~= "" then
             -- we're done
         elseif find(architecture,"x86_64",1,true) then
             platform = musl and "linuxmusl" or "linux-64"
         elseif find(architecture,"ppc",1,true) then
             platform = "linux-ppc"
         else
             platform = musl and "linuxmusl" or "linux"
         end
         os.setenv("MTX_PLATFORM",platform)
         os.platform = platform
         return platform
     end

assuming that the user or setuptex sets the path right this will cover 
runtime

that still leaves an issue for the initial mtx-update but that one can 
set MTX_PLATFORM=linuxmusl
