I don't think you understand the current build system.  How many times
have you built Syslinux from just source?

Incorrect use.

Yes and Yes

I'd be completely surprised if a working object ever comes out of that
unless aligned.

The firmwares FORCIBLY set these.  See 1408e6ca

To my knowledge, "make" with some special sauce that just marks the
binary with proper versioning.

I don't use git, so I have always downloaded a tarball, expanded it and 
built from the resulting root directory when needed. For the most part, 
I have used 'make installer' only, but not always. OTOH, I am not a 
package maintainer, I don't use additional building scripts (nor 
equivalent unattended methods), I am not building for others, and I am 
not cross-compiling.

The text in that commit doesn't really answer the questions *to me*, 
and it also includes some inaccurate phrases. That commit also 
introduced the ".bios/" sub-directory, which is, still today, a source
of confusion and additional problems for many.

Anyway, I'll be glad to see known issues resolved sooner rather than 
later; unfortunately there seem to be too many of them.
