Both the current libc and libm define isnan(), which causes a namespace
clash when linking programs with libm.

Witness /usr/src/bin/ps:

# make
cc  -static -o ps devname.o keyword.o nlist.o print.o ps.o -lm -lkvm
multiply defined: _isnan, type 0x1
s_isnan.o: Definition of symbol _isnan (multiply defined)
multiply defined: _isnan, type 0x1
isinf.o: Definition of symbol _isnan (multiply defined)
*** Error code 1

Stop.
