This set of options is seriously wrong if you want to build an SMP 
application for a LEON3 BSP.

For C99 multi-threaded programs are undefined behaviour.  Thus, use at 
least -std=gnu11.

In addition, you must use the machine options of the BSP, see 
c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg (-mcpu=leon3 
-msoft-float).
