166# avoids accidentally linking any kernel symbol against host platform
167# libraries.  The only non-renamed symbols are linkset delimiters and
168# the GOT, which are more a property of the compiler than the kernel.

173# the toolchain.  Worse, they vary from platform to platform and

175# be detected by a compile-time failure, so we can fairly easily manage
176# a quirktable here.
