bug#54793: guile-fibers does not cross-compile

[Mathieu Othacehe]

Hello,

guile-fibers does not cross-compile, the error is the following:

--8<---------------cut here---------------start------------->8---
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure dlopen: file "/tmp/guix-build-guile-fibers-1.1.0.drv-0/fibers-1.1.0/.libs/epoll.so", message "/tmp/guix-build-guile-fibers-1.1.0.drv-0/fibers-1.1.0/.libs/epoll.so: wrong ELF class: ELFCLASS32"
--8<---------------cut here---------------end--------------->8---

It breaks the build of novena, pine64 and pinebook-pro images, see:
https://ci.guix.gnu.org/eval/216001?status=failed.

Thanks,

Mathieu

I pushed cross-compilation support upstream:

  c4756b9 epoll: Do not refer to 'epoll.so'-provided variables at expansion time.
  393ecc6 build: Pass '--target' and '-L' to 'guild compile' when cross-compiling.
  e5fa008 build: Do not load 'epoll.so' during cross-compilation.

… and an equivalent fix in Guix:

  1f82602153 gnu: guile-fibers@1.1: Support cross-compilation.

Thanks!

Ludo’.
