Xcode 15 beta and macOS Sonoma beta show the following warnings with make

(snip)
linking miniruby
ld: warning: ignoring duplicate library '-lpthread'
miniruby: replacing existing signature
exe/ruby: replacing existing signature
builtin_binary.inc updated
compiling builtin.c
linking static-library libruby.3.3-static.a
linking ruby
ld: warning: ignoring duplicate library '-lgmp'
ld: warning: ignoring duplicate library '-ldl'
ld: warning: ignoring duplicate library '-lobjc'
ld: warning: ignoring duplicate library '-lpthread'
ld: warning: ignoring duplicate library '-lpthread'
(snip)

I'm not investigate that yet. It may be caused by ld-prime that is new linker of macOS platform.
