MIPS: lib: strlen_user: Use macro to build the strlen_user symbol
Build the __strlen_user symbol using a macro. In EVA mode we will need to use similar code to do the userspace load operations so it is better if we use a macro to avoid code duplications. Signed-off-by: Markos Chandras <markos.chandras@imgtec.com>
