When I tried it a few years back, I did it the 'hard' way: modifying the 
makefile of each project to add the extra linker flag. It was very 
tedious and I only did a handful of packages.

A better approach is to change the gcc wrapper. I believe that is what 
Douglas Paul did (see

And I have noticed that there is a similar patch, for newer gcc, that is 
carried in the Yocto/openEmbedded project streams.

Evidently not yet. Yesterday I built with gcc-7.4.0, and today I have 
done another build with gcc-8.3.0. Both versions are producing armv4 
binaries without need for any special linker flags.

I had read the same lkml thread, while trying to remember about the 
--fix-v4bx option. But I don't think that patch actually got merged into 
the mainline.
