I'm not clear what your root filesystem for qemu looks like
(the contents of /lib are the interesting part).
An ls -l of that directory would be useful.
It *should* look like this:
/lib
/lib/ld-musl-i386.so.1 # either file or -> /lib/libc.so
/lib/libc.so # only if ld-musl-i386.so.1 is symlink
/lib/libstdc++.so.6
/lib/libgcc_s.so.1
Note the version numbers.
All of these should be chmod 0755.
The libraries are ordinarily symlinks to the real ones:
$ ls -l /usr/lib/libstdc++.so*
lrwxrwxrwx 1 root root 19 Dec 30 15:27 /usr/lib/libstdc++.so -> libstdc++.so.6.0.20
lrwxrwxrwx 1 root root 19 Dec 30 15:24 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.20
-rwxr-xr-x 1 root root 845592 Dec 12 01:38 /usr/lib/libstdc++.so.6.0.20
If they are symlinks, check that the symlink target is also present.
