incorrect __vxworks__ usage in longlong.h (3.3) was ok in 3.2.3

[Ken Faiczak <kfaiczak at sandvine dot com>]

Not sure how this creeped in but it breaks all vxworks builds
for anything else other than PPC (in my case MIPS)

it really needs to be removed.
better to force the vxworks build to define __powerpc__ or something like
that
than to break the compiler for all vxworks builds that define stuff
before this point in the file..


from longlong.h


/* FIXME: We should test _IBMR2 here when we add assembly support for the
   system vendor compilers.
   FIXME: What's needed for gcc PowerPC VxWorks?  __vxworks__ is not good
   enough, since that hits ARM and m68k too.  */
