As a professional engineer, I'm conditioned to treat such claims with 
suspicion; it's inconsistent with the behaviour I see for every other 
regular DLL built for Windows, so I'd like to see concrete evidence in 
support of the claim.

What does that mean?  The makefile rules to build libgnat-6.dll, and 
libgnarl-6.dll, don't use gnatdll; they use "gcc -shared ...", just as 
any C language (or indeed any other language) DLL is built, and such 
DLLs don't cease to be relocatable when stripped.

Viewing my build.log in "less", and searching with "/libgna[tr]l*-6", 
is sufficient to show me those "gcc -shared ..." commands, and takes 
only a few seconds.
