Switch armv4l from NPTL back to pthreads instead of trying to patch uClibc into submission just now. arm-oabi is legacy support, need to swap the stack unwinding type to get NPTL to work with it.

DESCRIPTION=" ARM v4, little endian, soft float, OABI. This is a generic low-end arm image that should run on any arm hardware still in use today (except ARMv7M, which is arm in name only). The downside is it uses the Old Application Binary Interface, described here: http://www.linuxfordevices.com/c/a/Linux-For-Devices-Articles/Why-ARMs-EABI-matters/ This instruction set cannot support EABI, which requies the Thumb extensions. It's sort of the 80286 of the ARM world.
