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

170# satisfied by the toolchain itself when the program is linked.

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