Change subject: loader: Add volatile to resource_being_loaded.
......................................................................

loader: Add volatile to resource_being_loaded.

Some compiler optimizers seem to assume that dlopen will not use
__attribute__((constructor)) functions to call back to the program.
This was causing resource_being_loaded to be optimized away completely.
