Please use only --whole-archive as last resort :-(

I have found a linker option which seems to be exactly what you need. 
The option -u can force a reference to an external symbol which may be 
defined inside a library. You have to:
- use the form -Wl,-u on the GCC command line to pass that option down 
to the linker
- put that option *before* the library containing the definition
- prepend the function name with an _ as the linker deals with assembler 
symbols

Thus, try the following instead of your quote above:
-Wl,-u,_sdl_register_frontend -lnsfb -lsdl -lgem -lldg -lgem

Everything should be good and optimal.
