For the record there was one other issue with building glibc with
current GCC6 was:
tst-endian.c: In function ‘do_test’:
tst-endian.c:22:30: error: self-comparison always evaluates to false
[-Werror=tautological-compare]
if (htole16 (le16toh (i)) != i)
^
which is fixed by:
diff --git a/string/tst-endian.c b/string/tst-endian.c
