Hello,
uClibc-ng 1.0.50 + Linux headers 4.4 fails to build with:
In file included from ./include/sys/syscall.h:33, from ./ldso/include/dl-syscall.h:12, from ./ldso/include/ldso.h:52, from ldso/ldso/ldso.c:32: ./ldso/include/dl-syscall.h: In function '_dl_fstat': ./include/bits/syscalls-common.h:34:63: error: '__NR__dl_fstat' undeclared (first use in this function); did you mean '_dl_fstat'? # define INLINE_SYSCALL(name, nr, args...) INLINE_SYSCALL_NCS(__NR_##name, nr, args)
This is reproducible with Buildroot's arcturus_ucp1020_defconfig, and a log is visible at:
https://gitlab.com/buildroot.org/buildroot/-/jobs/8864051076
With the full log at:

Any clue?
We enabled time64 by default in uClibc-ng a while ago. With 1.0.51 you will get: #error 64bit time on 32bit targets is not supported on Linux < 5.1.0
We somehow need to handle UCLIBC_USE_TIME64 inside Buildroot and disable it for Linux < 5.1.0 systems.
Any idea how to manage it?
