Hi,
It looks like it is the SAMPLE_FLAGS which are missing the options. Applying
the patch below caused my building of the sample shell (scons sample=shell)
to do
g++ -o obj/sample/shell/release/shell.o -c -fprofile-arcs
-ftest-coverage-O2 -m32 -Iinclude samples/shell.cc
g++ -o shell -m32 obj/sample/shell/release/shell.o -L. -lv8 -lpthread
-lgcov
