# Rename library symbols before use.  If a symbol does not already belong
# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
# avoids accidentally linking any kernel symbol against host platform
# libraries.  The only non-renamed symbols are linkset delimiters and
# the GOT, which are more a property of the compiler than the kernel.
