Illustrate a redirector using the example of round function from math.h.
Setup demonstrated in this patch is only for ELF-ish platforms.
Also note:
1. Use of redirectors is a temporary scheme. They will be removed once
LLVM-libc has implementations for the redirected functions.
2. Redirectors are optional. One can choose to not include them in the
LLVM-libc build for their platform.
3. Even with redirectors used, we want to link to the system libc
dynamically.
