we already solved this issue via ST but I'll still post the result here 
for reference: to prevent this particular error, you'll need to also 
provide the additional linker option -coverage.

As not all ltp Makefile work well when specifying CFLAGS and LDFLAGS on 
the make command line, you'll need to specify those during the configure 
step, i.e.

./configure CFLAGS="-fprofile-arcs -ftest-coverage" LDFLAGS="-coverage"
make
