The glibc build is almost certainly buggy and reliable on things GCC does
not guarantee.
The options you quote don't include -fno-unit-at-a-time. glibc should be
using this option (or, better, -fno-toplevel-reorder with newer GCC) to
compile this file; I don't know how you configured it not to use this
option. glibc's configure tests for and should have detected
-fno-toplevel-reorder support.
