.jcr still needs a 0-entry added in crtend, even on !HAVE_CTORS archs, as
we're still getting .jcr sections added -- presumably due to the reference
in crtbegin. Without this terminal, the .jcr section (without data) overlaps
with the next section and register_classes in crtbegin will be examining the
wrong item.

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the
.init/.fini section. The latter just needs to call a gcj specific function
if it exists with a pointer to the start of the .jcr section.
This is currently disabled until __dso_handle support is added.

C function so the compiler won't try to emit line numbers for it
with "-g", breaking the build. This has the nice side-effect of
making crtbegin.o and crtbeginS.o a little bit smaller.
Remove "-Wno-unused" from the Makefile. Replace it with "__unused"
on particular function and variable declarations.
