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.

Mircea, All,

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?
Regards,
Yann E. MORIN.

Hi Yann,
Your proposal looks good: it's cleaner + it covers everything supported
by uClibc-ng.
I also tested with my configuration and it seems fine.
Thanks and regards,
Mircea Gliga

Synchronize the list of architectures that have LinuxThreads support
with the ones from uClibc-ng.
Signed-off-by: Mircea GLIGA <mgliga@bitdefender.com>

Changes v1 -> v2:
- enable linuxthreads for all supported architectures,
not just MIPS (suggested by Yann E. MORIN)
