[arrowdodger]

I'm on FreeBSD 8 (GCC 4.2.1) and building TOT compiler-rt using cmake. This
is what i get:
[ 89%] Building C object
test/CMakeFiles/powidf2_test.dir/Unit/powidf2_test.c.o
Linking C executable
powidf2_test
CMakeFiles/powidf2_test.dir/Unit/powidf2_test.c.o(.text+0x47): In function
`test__powidf2':
: undefined reference to `__signbit'
