Nothing from <machine/asm.h> is even used here, so don't include it.
...
This was the only place in the system where asm.h contents were seen
by the compiler and hence the only reason why asm.h had to conform
to C syntax. This previously limited asm.h to a cpp constructs and
comments.

powerpc64 assembly for .init / .fini

Remove the call to init_fallthru/fini_fallthru and call _init/_fini
...
directly for MIPS. Making these global to keep gcc4 happy broke gcc3.
Shaves a few instructions off this path as well.
Other arches to follow with similar changes.
With much help from Nick Hudson.

add a .globl to MD_SECTION_PROLOGUE so that the symbol is exported.
...
this fixes build problems with GCC4 (which will use smaller/faster call
methods for local/static functions) and is the right thing anyway.

remove support for building (with) GCC 2.95. also:
...
- always install <stdbool.h>
- don't generate a fake one for vax / gettext.

Instead of using -I- -I${.CURDIR} and #include "dot_init.h", use:
...
-I${.CURDIR} and #include <dot_init.h>, since -I- is obsoleted in gcc-4,
and it is too confusing anyway.

Fool gcc to compare against a null variable instead of the NULL constant

Avoid weak symbol related bug with _DYNAMIC not being referenced in the

code at all for gcc-4. Fixes statically linked binaries, but the fix is
bogus.

with GCC4 we *need* to pass -fno-unit-at-a-time otherwise GCC
...
reorders things breaking _init() and _fini().
for i386, the {init,fini}_fallthru() functions were being output
_before_ the _init()/ _fini(), and instead of falling through to
the rest of the .init/.fini section, it would fall through to
_init()/_fini() again, and again, and again, until the stack was
exhausted.
now i386 works, but i have not checked that this works for
sparc64 as well.
