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

181# the toolchain.  Worse, they vary from platform to platform and
182# toolchain to toolchain.  The good news, however, is that this will
183# be detected by a compile-time failure, so we can fairly easily manage
184# a quirktable here.
