[PATCH] Fix compilation error with older versions of gcc

[Matthew Leach]

Some versions of gcc will error if you define a type twice (even if
the definition is the same). The ncr53c8xx scsi driver defines
'vm_offset_t', this is also defined in mach_types.h and will therefore
cause a compilation error depending on the gcc version.

* linux/src/drivers/scsi/ncr53c8xx.c: exclude the typedef's if we are
  executing a mach build.
