various architectures. Now all the work is done in crtbegin.c.
It doesn't contain any assembly language code, so it should work
fine on all architectures. (I have tested it on the i386 and the
alpha.) The old assembly language files crt[in].S are now empty
shells that generate no code or data. They should not be removed
any time soon, because the various versions of gcc in src and ports
expect them to exist.
Next I will move crtbegin.c into a new common machine-independent
directory, and adjust the i386-elf Makefile to use that version.
After that I will adjust the alpha Makefile to use the common
version too.

shared library when invoking global constructors and destructors.
For constructors, the object files used to be processed from first
to last; now they're done from last to first. (Destructors are done
in the opposite order, as required by the C++ standard.) This makes
us consistent with standard gcc and egcs compilers. It also
eliminates ordering differences between dynamic and static
executables.
Bump the value of __FreeBSD_version to 400002 to reflect this
change.
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.
