[PATCH] alpha: Fix clone exit syscall argument passing (BZ#21512)

[Adhemerval Zanella]

This patch fixes the argument passing for exit syscall after
the clone function returns on hppa.  This fixes misc/tst-clone2
on alpha-linux-gnu.

Checked misc/tst-clone2 on alpha-linux-gnu.  I will commit this shortly if
no one opposes.

	passing to syscall exit.
