Hello,
in order to fix #229357 I decided to add a new Build-Options field.
I modified Dpkg::BuildOptions to parse this field and DEB_BUILD_OPTIONS.
And I added support for a build-arch option, that if present, will let
dpkg-buildpackage call debian/rules build-arch and build-indep.
It's not obvious that this was the right choice when you think of the
currently existing build options but once you start thinking of possible
additions (as requested in #489771), it becomes more evident that it makes
sense. Even if some build options should really only be used in
the field while others should only be used in the environment variable,
the possibility to override the former with the latter is nice.
The current patchset is available in my public repository but I'll attach
it as well so that you can easily review it. I intend to merge it this
week-end after some tests but feel free to test and comment in the mean
time.

The patchset only applies on top of master.
Cheers,

Subject: [PATCH] Refactor Dpkg::BuildOptions to handle Build-Options field
* scripts/Dpkg/BuildOptions.pm: complete rewrite of the module
to handle various sources of build options: some options are auto-set
based on the standards version, then the maintainer can define options
with the Build-Options field in debian/control and last the builder
can use DEB_BUILD_OPTIONS to override everything. Some options are
meant to be exported through DEB_BUILD_OPTIONS and some are not.
* scripts/t/300_Dpkg_BuildOptions.t: adjust test suite for the new module
* scripts/dpkg-buildpackage.pl: adjust to use the new Dpkg::BuildOptions
API.
* scripts/Dpkg/Fields.pm, scripts/Dpkg/Source/Package.pm: add the new
Build-Options field as a valid field in the source section of
debian/control (and in .dsc files).
