elfutils issues when building systemtap rpm from snapshot on rawhide

[William Cohen <wcohen at redhat dot com>]

When attempting to build a systemtap rpm with elfutils-0.116 and a 
snapshot of the systemtap I ran across a problem on i386 rawhide. I did 
not see this problem when building the elfutil-0.116-1.src.rpm nor was 
it a problem on FC4. Below is the portion of the output listing the 
error messages and the problem lines in line2addr.c from the attempted 
rawhide build.

looks like it should be:

In some versions %a spec allocates memory, but in the rawhide compiler
(C99) it is equivalent to %f and causes a mismatch.
