Allow compilation with ASAN
Compiling with ASAN can help find improper memory management by detecting
leaks, use after frees, double frees, buffer overflows, etc.
It will profile the binary which has an effect on the binary size and
possibly a small impact on performance (although a lot better than valgrind).
We can use this from GCC-4.8 onwards.
To enable, during configure time, run:
./configure --enable-asan

Limitations (Pulled from Clang docs, but should be similar for GCC):
https://clang.llvm.org/docs/AddressSanitizer.html#limitations
