This patch is not relative to current glibc. You'll also need to explain
why the
# These files quiet sNaNs in a way that is optimized away without
# -fsignaling-nans.
CFLAGS-s_modf.c += -fsignaling-nans
CFLAGS-s_modff.c += -fsignaling-nans
CFLAGS-s_modfl.c += -fsignaling-nans
in math/Makefile isn't working, as it is for all the similar
implementations and other architectures.
