--- Comment #12 from Rich Felker <bugdal at aerifal dot cx> ---
For musl libc.a, neither stdin.o nor fflush.o should be pulled in unless
they're actually used. For stdin.o, that means referencing stdin itself or a
function (like scanf or getchar) that explicitly uses stdin. For fflush.o, the
users are assert, getpass, fclose, freopen, and the stdio_ext.h functions. So
this seems wrong:
> it seems they're getting pulled in via crt1.o -> __libc_start_main -> exit
As for:

Won't -Wl,-M do this? Or you could just look at a non-stripped output binary
with debug symbols, which should show the object file filenames that were
linked.
