Subject: [PATCH 0/6] package/pseudo: fix build and better mimic fakeroot

Hello All!

When we switched from using fakeroot to using pseudo, a lot of assumptions were made, in that we assumed pseudo was by default behaving as fakeroot did.

That is wrong. pseudo is a little bit more versatile than fakeroot is, so using it is a little bit more involved.

First, its buildsystem is a bit convoluted, and can incorrectly guess the host charateristics, like bitness.

Second, it needs to be told at runtime where to look at, and put its own stuff. It correctly gueses, but prints a warning that it had to gues, and the location to store its DB is not optimum (even if not incorrect).

So, this series ensures that pseudo is correctly built and that we correctly specify the runtime configuration.

I build my firmware inside a Docker container, in which a minimal Ubuntu x86-64 distro runs with no libc6-dev-i386 installed. However, '-m32' was polluting the compiler options and the x86-64 headers couldn't be found. This patchset fixes the build.
