# 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.
#
# Some toolchains generate unresolved symbols which are supposed to be
# satisfied by the toolchain itself when the program is linked.
# Unfortunately, we do not know which of the symbols are generated by
# the toolchain. Worse, they vary from platform to platform and
# toolchain to toolchain. The good news, however, is that this will
# be detected by a compile-time failure, so we can fairly easily manage
# a quirktable here.
#
# We also allow calling ourselves externally with e.g.:
# make -f /sys/rump/Makefile.rump RUMP_SYMREN=ffs.kobj

# complaints about symbols like 'rumpns_XrumpBLAH' or 'XrumpBLAH';
# the 'X' part was added by the toolchain and will need to
