I already sent v2 with different approach. Problems boils down to beep's
GNUMakefile trying to figure out whenever compiler supports various
sanitizers flags, but fails to figure out, that it comes at price linking
with sanitizer libraries on some architectures. V2 solves that by removing
all those checks, so external libraries are no longer needed.
