ASAN: set MAXIMUM_OVERDRIVE := true to disable address sanitizer

with respect to BONE_STOCK taking priority.

Address sanitizer is a debugging tool that detects memory errors in the program through debugging tools
like gdb. It does so by using an extra instrumentation module llvm pass during compilation and a runtime
library that replaces the malloc function and by inserting frame pointers in the stack.

Output code performance can be effected if a "hot" function that is known to speed up the code gets
flagged during the extra compiler pass.  This also potentially can reduce build time.
