# TODO(vbendeb): the below statement is a hack required to circumvent the
# build system deficiency: the linker default library path is specified in
# /build/<target>/make.conf, which causes the system libraries to be examined
# first by the linker, not last, as they ought to be.
#
# Once the build system is fixed the below statement will be removed to allow
