At first you have to change the RHIDE link spec (the next version will
have this changed) by adding the following to your global/local
rhide.env file:

RHIDE_COMPILE_LINK=$(RHIDE_LD) $(RHIDE_LIBDIRS) $(C_EXTRA_FLAGS) -o \ 
$(OUTFILE)\$(OBJFILES) $(LIBRARIES) $(RHIDE_LIBS) $(LDFLAGS)
$(RHIDE_LDFLAGS)

NOTE: This should be written on _ONE_ line _WITHOUT_ the \

and then you can put in the "Options/Linker options"

-( -lfoo1 -lfoo2 -)

There should be no difference in functionality, but for me it is betther
to create the linker options with

$(addprefix -Xlinker ,$(LD_EXTRA_FLAGS))

instead of creating a string, which contains the commas, since the
commas hava a special meaning in the RHIDE specs (and the corresponding
GNU-make string-functions).
