Mircea, All,
On 2021-05-21 12:59 +0300, Mircea GLIGA spake thusly:
> Required for systems that do not have FUTEX support in kernel.
> Native POSIX Thread Library (NPTL) relies on futexes, so we need
> to use LinuxThreads instead on that systems.

I was a bit annoyed by this very logn line, so I took the liberyty to
split it, but then I looked at uclibc-ng for the list of architectures
that still has LT support, and it turns out that almost all do, except:
- AArch64 (both endianness)
- riscv64
- metag (irrelevant for Buildroot)
So I think it would be better to change the way we expose BR2_PTHREADS
for uClibc:
config BR2_PTHREADS
bool "linuxthreads"
depends on !BR2_aarch64 && !BR2_aarch64_be
depends on !BR2_RISCV_64
Could you please respin with this, please?

Yann E. MORIN.
