 From https://www.gnu.org/software/libtool/manual/libtool.html#Tags
 
 "The tag can also be specified using libtool's --tag=tag option (see
 Invoking
 libtool). It is a good idea to do so in Makefile rules, because that
 will allow
 users to substitute the compiler without relying on libtool inference
 heuristics. When no tag is specified, libtool will default to CC; this
 tag
 always exists."
 
 So maybe it's not so bad explicitly giving --tag=?
