[ARM] 2941/1: Fix running legacy binaries from a soft-float root filesystem with CONFIG_IWMMXT.
Patch from Daniel Jacobowitz
Thread flags are inherited on fork(). In order for a binary which has
the iWMMXt coprocessor enabled to run a binary which needs the FPA
emulation, we need to explicitly clear TIF_USING_IWMMXT if we are not
going to set it.
