If for example you want to use the thread sanitizer you want to ensure all
binaries are linked with the library:
./configure ${TARGETS} --cc=gcc-5 --cxx=g++-5 \
--extra-cflags="-fsanitize=thread" --extra-libs="-ltsan"
This is more explicit than just specifying --extra-ldflags which does
not get applied at the end of the linker string.
