sparc: only define start if it is different from SYM(start)

Browse Source 
The SYM define concatenates the input with the compiler set
__USER_LABEL_PREFIX__ define. This define appears to be '_' in GCC but
empty in Clang. Therefore when compiling with Clang/LLVM 'SYM(start)'
and 'start' defines the same symbol, and the compiler complains that the
symbol is defined twice.
