[PATCH] D54681: [Driver] Avoid including -lm on the link line with -nostdlib++

Drivers include -lm because standard C++ libraries such as libc++
and libstdc++ depend on libmath and when statically linking C++
library, this dependency is needed. However, when -nostdlib++ is
used, there's no reason to include -lm anymore.
