glibc build failure due to Systemtap probe change

systemtap can now extract and store floats as long type and do basic 
operations so static markers now tag a float arg with a 'f'.

Hmm, so __longjump is creating its own STAP_PROBE_ASM_TEMPLATE?  Adding 
the arg type was difficult for even the baroque sdt.h macros to handle 
so some of the functionality was pushed into gas macros where compiler 
results can be observed instead of simple source text.  So the resulting 
template is now considerably more complex.
