Someone needs to adjust how the parisc kernel is built on kisskb...

The parisc platform got vDSO support, so now the 32- and 64-bit
hppa compiler needs to be installed when building (for 64-bit).

In addition, it changed how to build a kernel:
 make ARCH=parisc                         # to build a 32-bit kernel
 or
 make ARCH=parisc64                       # to build a 64-bit kernel
(before ARCH=parisc was sufficient to build either for 32- or 64-bit).

And, in case "CROSS_COMPILE=" is given, you need to give "CROSS32_COMPILE=" as well.
It's preferred to leave out both CROSS[32]_COMPILE= parameters and let
the environment detect the compilers automatically. They just need to be in $PATH.

Who can change that on kisskb ?
