I get that warning on my box too.
CFLAGS="-march=amdfam10 -O2 -pipe" in my case.
Standard FEATURES.
I think there is an "#include <math.h>" missing.
I also get the following error:

note: 'sin@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try
adding it to the linker command line
/lib64/libm.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
I have fixed these types of bugs before so I can fix it. The -lm is missing..
