efl: add compiler flags 

* -fvisibility=hidden will hide symbols not marked with EAPI in the
    final binary (so/executable).

 * -ffunction-sections and -fdata-sections will split those into
    independent elf sections, then we can -Wl,--gc-sections for those
    that are unused. During development --Wl,--print-gc-sections will
    warn us of functions that are left unused and were collected.
