kbuild: warning fixes on Solaris 9

The following set of patches is based loosely on the patches that
Jean-Christophe Dubois came up with for 2.6.7.  Where as the original
patches added a number of casts to unsigned char, I went the route of
making the chars be explicitly signed.  I honestly don't know which
route is better to go down.  Doing this is the bulk of the patch.  Out
of the rest of the odds 'n ends is that on Solaris, Elf32_Word is a
ulong, which means all of the printf's are unhappy (uint format, ulong
arg) for most of the typedefs.
