    Define static user probe point using asm instead of c.
    
    * includes/sys/sdt.h (STAP_PROBE_DATA): New.  Define the probe point
    using asm instead of c.
    (STAP_PROBEN): Use it.
    * testsuite/systemtap.base/sdt.exp: Continue if a compile fails.
    * testsuite/systemtap.base/static_uprobes.exp: Don't test setting
    probe without .probes section.

sdt.h doesn't compile anymore on i386.
