Apparently the has_attribute() macro triggers false positives on at
least gcc 5.3, which is the version that the build server uses with
djgpp.
Drop using it, so much for trying to be standards-compliant...

It is sometimes just too convenient to be able to convert between
strings and bytes at will. At one point I was considering making
something with the full power of the db (et al) directives, but that
is a much bigger change...

The external call to hexdump was broken and would hang if the output
exceeded the host operating system size limit. Since it *anyway*
was reading the entire dump into RAM, just rewrite it in native
Python.

S_ISREG() is usually a macro, it needs PA_HAVE_FUNC().
Don't bother checking for functions related to struct _stati64 if that

Older versions of NASM would not try to match unknown %if directives
with a corresponding %endif, resulting in some very odd consequences
when it comes to trying to handle support for multiple NASM versions.
Document the problem.

If an unknown preprocessor directive starting with %if or %elif is
encountered, assume it should be treated as a conditional directive
for the purpose of balancing %if...%endif.
This avoids some really ugly problems when dealing with code that is
intended to work across NASM versions that uses %if directives that
don't yet exist.
