2d62241cb9 Reorganization of crtbegin/crtend. 
o  Primary mod: alpha and i386 code for .init and .fini section fallthroughs
o  Actual fallthru is not yet enabled, see csu/{alpha,i386_elf}/Makefile
o  When enabled, should fix bin/12865 & should fix at least one WINE bug,
   see http://www.winehq.com/hypermail/wine-devel/2001/05/0021.html
o  Also, removed the function pointer hack put in to prevent gcc from
   incorrectly attempting to do short calls over section boundaries,
   on some architectures, rather, simply simply move ctors() and dtors()
   into .init and .fini.
Other notes.
o  Our crtbegin.c and crtend.c were completely in C, despite
   the fact that .init and .fini section fallthroughs require machine code.
   These modules implement the gnu ctors/dtors mechanism directly, eliminating
   in part the need for the elf .init/.fini section fallthrough. However,
   if we ever want to use the gnu-provided constructor support, we need to
   do the fallthrough, at least one program (WINE) apparently uses the
   feature independently, and other compilers may depend on the mechanism.
o  It is amusing that the previous NetBSD _init() and _fini() were put
   into the .init and .fini sections, because nothing is gained over
   plain .text if they don't fall through. Cargo cult!
o  Other elf ports will need to copy the alpha and i386 example mods.

773ab1dd74 Put back __RCSID(): The problem was that if RCSID ended up in the text segment, 
it was placed before `start', and start ended up misaligned. Add an alignment
directive for the start symbol. Of course ld(1) should not core-dump relocating
misaligned symbols, but this will be fixed shortly.

jonathan
f4aee0fcbb New, Alpha-derived crt0.c with ld.elf_so support. 
Expects additional register-passed arguments from the kernel on
exec().  If no such args ($a0 is zero), fall back to the old hack of
adjusting the current $sp with a hard-coded frame offset for __start's
local frame(!).

Suggested by Jason Thorpe (thorpej@nas.nasa.gov), debugged and
stackframe offsets updated by Jonathan Stone.

5fd7ce7066 These updates to the build allow building against include files 
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.

53ded8ebcb add a hack so that old- and new-toolchain alphas do the right thing: 
include bsd.own.mk early on, and if !alpha or if !ELF_TOOLCHAIN,
build c++rt0.o.  ELF alphas don't use the 'normal' C++ runtime startup
routines.  Eventually, there should be better ways to distinguish what
toolchain and object format is in use, and the Alpha C++ startup code
changes should be merged with that used by the other ports.
