[PATCH]Add include guard to sparc.h when using assembly

[Mohammed Khoory]

Please ignore my patch. It seems that I found the problem in rtems-4.10.2,
which is what I'm working with, and I thought I had found the same problem
in git, so I decided to send in the same fix I did for 4.10.2.. but it seems
that this issue isn't there in the git version because everything seems to
be included correctly. 

Basedefs.h does have an include guard around stdint.h and the other include
lines, so I don't think there's a problem there.

Sorry for any time wasted. I'll try harder to make sure that my patches are
sound next time.
