[Buildroot] [PATCH] disable linuxthreads for NPTL only architectures for uClibc-ng

uClibc-ng does not support multiple thread implementations for
an architecture and MMU configuration.
BFIN, ARM noMMU and m68k/Coldfire noMMU still uses linuxthreads in uClibc-ng.
The other buildroot supported architectures support NPTL.
Reflect this in Buildroot configuration.
ARC would work with uClibc-ng 1.0.0 and TLS/NPTL, but the correct
toolchain must be used.
