Seems to come from:

all/x25519-1.0.8/ext/x25519_precomputed/extconf.rb:
  $CFLAGS << " -Wall -O3 -pedantic -std=c99 -mbmi -mbmi2 -march=native -mtune=native"
ruby25/x25519-1.0.8/ext/x25519_precomputed/extconf.rb:
  $CFLAGS << " -Wall -O3 -pedantic -std=c99 -mbmi -mbmi2 -march=native -mtune=native"

    dev-ruby/x25519: precomputed impl only works on amd64
    
    The precomputed implementation only works on amd64, so avoid it
    on other arches and let them fall back to the unoptimized reference
    implementation.
