d8abc59932 Add support for invoking GNU C++ local destructors in shared objects 
via the __cxa_finalize() mechanism.

XXX Only enabled for new-toolchain platforms, as it requires the assembler
to support the .hidden pseudo-op.

a50163af65 Build separate crt{begin,end}.o and crt{begin,end}S.o files, rather 
than linking them at install time.  Forthcoming changes require different
behavior for static vs. shared object versions of these files.

f768a5c42b Reduce the alignment constraint from 4 to 2. This fixes the problem where 
gas(2) pads the text segment with 0x0 instead of NOP. Since m68k instructions
only need 16-bit alignment, .align 2 works just fine.

9a68629ca6 Enlarge the stack frame to 16 bytes, and store the return address 8 
bytes in instead of at the start, to leave room for a .cpload to store
the gp at offset 0 in the frame.  Allow 8 bytes for each (for mips64
one day...).

.cpload overwrite problems noted by Michael Hitch.

the internal __start to ___start.   (Since -e is not supplied by default,
this has no effect on a native build.)

a6855eea24 Add support for DWARF2 frame unwinding/exception handling. This

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.
