Comment (by ryandesign):

 A comment in the ld64 portfile explains the reasons behind the default
 ld64 versions on different OS versions, specifically:

 {{{#!tcl
         } elseif {${os.major} < 15} {
             # os versions < 16 can't build libtapi or newer ld64 versions
 with their stock xcode compilers
             # so need to call in clang-9.0 and that has a runtime dep on
 ld64 (circular)
             default_variants +ld64_274
 }}}

 (There appears to be a disagreement on whether it's Darwin 15 or 16.)

 So, you could install a newer ld64 on older systems if you first install
 an older ld64 and, using that, install a newer clang.
