No, you don't need to rebuild glibc to use gcc vector extensions. Indeed
-mabi=altivec "extends the current ABI with AltiVec ABI extensions.
This does not change the default ABI, instead it adds the AltiVec ABI
extensions to the current ABI." (from the glibc info page).
You also need to build the program with -maltivec.
