Portage Errors: dev-libs/libaio final link failed: Nonrepresentable section on output

You may encounter output similar to this when compiling libaio (a dependency of multipath-tools) if you have enabled Stack Smashing Protection in your CFLAGS:

>>> Failed to emerge dev-libs/libaio-0.3.107

To remedy, temporarily remove any and all the following from your CFLAGS and recompile:

-fstack-protector -fPIE -fPIC
