systemtap build breaks, if CXXFLAGS="-g -fprofile-arcs -ftest-coverage" is set.

[Srinivasa DS]

I tried building latest systemtap-20080524 snapshot with CXXFLAGS="-g 
-fprofile-arcs -ftest-coverage" on x86_64 system(problem not seen on ppc 
systems), but build failed with below error message.

Steps
=======
1)./configure --with-elfutils=/home/systemtap/btils/elfutils-0.131/ 
CC='gcc -m64' CXX='g++ -m64'
2)make CXXFLAGS="-g -fprofile-arcs -ftest-coverage"
