While here: Factor out .section/.previous wrapper into a separate macro.
Provide frame pointer. Add the comment to MD_CALL_STATIC_FUNCTION to
explain why it needs semicolon and why we actually don't use that macro.

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.

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.

this fixes build problems with GCC4 (which will use smaller/faster call
methods for local/static functions) and is the right thing anyway.

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,

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.
