Hi Florian,

I've just recognized that building with -Os fails with
/usr/bin/ld: /path/to/glibc-build/libc_pic.os.clean: in function `fchmodat':
(.text+0xb1c36): undefined reference to `fstatat64'
collect2: error: ld returned 1 exit status

This happens at least on x86_64 and s390x.
I've bisected and this was the first bad commit.

Can you please have a look?

Bye
Stefan
