If you are re-implementing a function that exists in the standard ARM library, the linker
uses an object or library from your project rather than the standard ARM library. A
library you add to a project does not have to follow the ARM naming convention for
libraries.
Caution
Do not replace or delete libraries supplied by ARM. You must not overwrite the
supplied library files. Place your re-implemented functions in a separate library.
