# NOTE: valgrind requires rebuilt with each major glibc version

# NOTE: I had to run this after installing target-glibc to build target-gcc:
# for lib in /usr/${_target}/usr/lib/*; do
# ln -s ${lib} /usr/${_target}/lib/$(basename ${lib}
# done
# gcc build should probably add a -B flag to usr/lib instead
