Comment (by kencu):

 I had previously done this : {{{sudo port select llvm mp-llvm-7.0}}}

 It turns out that the {{{llvm-7.0}}} I had installed was not universal.

 Deselcting any llvm like this {{{sudo port select llvm none}}} also fixes
 the universal build.

 It appears that {{{llvm-ar}}} is being found if present, and if it's not
 universal, the build errors out. If {{{llvm-ar}}} is not found,
 {{{meson}}} falls back to {{{ar}}} it seems, and that works.

 note:
 {{{
 [5/74] rm -f droute/libdroute.a && llvm-ar csrD droute/libdroute.a
 'droute/8dce163@@droute at sta/droute.c.o' 'droute/8dce163@@droute at sta
 /droute-variant.c.o' 'droute/8dce163@@droute at sta/droute-pairhash.c.o'

 vs

 [5/74] rm -f droute/libdroute.a && ar csr droute/libdroute.a
 'droute/8dce163@@droute at sta/droute.c.o' 'droute/8dce163@@droute at sta
 /droute-variant.c.o' 'droute/8dce163@@droute at sta/droute-pairhash.c.o'
 }}}
