patch ia32 mode [Threads don't wake up in ia32 mode]

This is the solution to the problem I described in june,

see test case there:

l

There was an oversight on the size of the long, which caused an improper restoration of the real time signals blocking mask of the 32 bit frame, 2 of these signals are used by the pthreads library for wakeup or cancellation.

This patch can be applied to all 2.4.x series kernels including 2.4.7, since the file has not changed.

This patch looks correct to me, so I applied. Don, speak up if you object...
