Subject: [PATCH] Fix building kernel under Solaris


Fix varous build breakages that occur when building on a Solaris system
(SunOS 4.8 to be exact)

- No asm/types.h

- lpptest doesn't make sense on a Solaris host (this should really be
  cross-built..)

- Need to define __s32 and __s16

- Need to define Elf32_Section and Elf64_Section

- Solaris does not provide strsep
