168# to a rump namespace ("rump" or "RUMP"), prefix it with "rumpns".  This
169# avoids accidentally linking any kernel symbol against host platform
170# libraries.  The only non-renamed symbols are linkset delimiters and
171# the GOT, which are more a property of the compiler than the kernel.

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

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