From altogether too much searching around with gcc -M, it lookslike the problem is that openbios has in its include directory an asm/types.h. Because things added to the header search path by -I shadow system headers and are global, this replaces the <asm/types.h> that <asm/sigcontext.h> relies on, causing the error. On aarch64, <bits/sigcontext.h> (which I think <signal.h> includes?) imports <asm/sigcontext.h>, so the whole thing fails to build. On x86_64, <bits/sigcontext.h> does not import <asm/sigcontext.h>, so this whole problem never occurs.
I don't know how to fix this on guix's end, but I guess I now need to complain to upstream and hope they can work out a fix.
