c50be14baa Adjust stack alignment so that when the 'call xxx' functions are
gathered into the middle of the _init and _fini sections, they get
executed with their expected stack alignment.

ae7c8a2bb8 * Bring back the guts of crt{i,n}.S. This allows C++ exceptions to work
when using the egcs and gcc-devel ports, along with GCC built from stock
public FSF sources.  With out this change, FreeBSD will be removed from
the list of systems GCC 3.0 must be evaluated on before release.  With
the effort some of us put into getting FreeBSD on this list, we should
not turn this effort into a waste, else we might not be worth fighting
for in the future.  (note that Alpha and IA-64 versions of crt{i,n}.S
are needed)

* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c.
This will allow us to switch to DWARF2 exceptions in the future, along with
staying in sync with any future GCC requirements.

* Break out our ELF branding bits into a seperate file.  Currently this
is now included by our crt1.c files (since this functionality was part of
our native crtbegin.c).  Later crtbrand.o will be merged in the creation
of crti.o.

f6d15b87f8 This is step 1 in an effort to unify the start-up files for the
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.
