Application.mk: Give the program attributes to gcc with -Wl,.
With CONFIG_LTO_FULL (GCC), LD is the compiler driver, and a loadable
module (and a program of a kernel build) is linked with it, because
MODULELD defaults to LD. Application.mk gave the program attributes
as "--defsym nx_stacksize=...", and gcc stopped with "unrecognized
command-line option '--defsym'".
Where Application.mk sets MODLDFLAGS, it now also sets MODDEFSYM:
"-Wl,--defsym=" when MODULELD is gcc or clang, and "--defsym=" for ld.
A link with ld gets "--defsym=sym=value" in place of "--defsym sym
value", which GNU ld and ld.lld read the same way.
