Make further autoconf rule improvements and update the required
version of autoconf to 2.69. That version is now 5+ years old and
although there might be older versions which have the prerequisite
macros they are known to have lots of bugs, and we can't really test
them.

Make it possible to keep dependency information separate from the
Makefiles, so we don't have to deal with it noisifying the git logs.

autoconf complained about this dnl, and it's not necessary anyway (and

Add defines for added CFLAGS. This can be useful, for example, for
LTO or sanitizers being enabled.
Various cleanups for readability and documentation; use macros
available in current autoconf.
Add new utility function PA_SYM(), similar to AS_TR_CPP() except
collapses sequential underscores.

For specially formed code we can have skip_white_
to end up with nil pointer which should be taken
into account.

In case if smacro is called with inapropriate
number of arguments exit early. Actually we have
to handle this situation more gracefully but
this requires a way more efforts than two
line patches (need to refactor macro expansion).

For immediates, we had one overflow test in the bytecode interpreter
(in most cases via warn_overflow_opd()) and one in out(); this meant
we got two warnings instead of one every time. Replace with only the
one in out().

The calculation of vmin in overflow_general() was bogus, causing
silliness like ~80h being warned about in a byte context.

We could generate the MRI version (SSE 4.1) instead of the RMI

We need to always define the end symbol, otherwise we might find
ourselves in a situation where the alignment code grows (common!) and
then the symbol is defined late.

The DWARF spec specifies that the .debug_abbrev section always should
end with a null byte. Existing tools don't seem to care, but some
issue a warning, and it is invalid according to spec.

Some OMF toolchain can make use of file dependency information
embedded in the object files. As implemented here, we don't try to
absolutize the filenames, as that prevents moving around trees and is
OS-dependent.
