openbios-qemu-ppc fails to build on aarch64

openbios-qemu-ppc currently fails to compile on aarch64, with

build errors about missing __u32 and __u16 types somehow existing

in a linux header file that includes the header file that defines

those types. (Log attached.)

From altogether too much searching around with gcc -M, it looks

like 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.

(I have a newfound hatred of #include.)

I've submitted an issue to upstream:

It looks like from the other open issues, that the openbios team doesn't actually use the github issue tracker but their own mailing list, which I'm CC'ing, along with the qemu-ppc mailing list.

For anyone following this issue who wants to work around it and be able to `guix system reconfigure` on aarch64, I've copied the qemu package definition from before Marius unbundled a bunch of the qemu firmware, including openbios, to here:

The relevant parts of my system config are then

(use-modules (akira qemu))

(define %qemu-package-replacements

`((,qemu-minimal . ,my-qemu-minimal)))

(define with-my-qemu

(package-input-rewriting %qemu-package-replacements))

(define my-grub-efi

(with-my-qemu grub-efi))

(define my-grub-efi-bootloader

(bootloader

(inherit grub-efi-bootloader)

(package my-grub-efi)))

(operating-system

...

(bootloader (bootloader-configuration

(bootloader my-grub-efi-bootloader)

(targets '("/boot"))

(keyboard-layout keyboard-layout)))

...)

Fixed as of 042b92edb20648c030dcbaf59acd176731550b70
