[PATCH 3/5] parisc: Fix signal code to depend on CONFIG_COMPAT instead of CONFIG_64BIT

[Helge Deller <deller@kernel.org>]

From: Helge Deller <deller@gmx.de>

The signal handler code used CONFIG_64BIT to decide if compat handling
code should be compiled in. Fix it to use CONFIG_COMPAT instead.
This allows to disable CONFIG_COMPAT even when running a 64-bit kernel.
