Hey,

es=E2=80=99)
> what is referencing these two cross-compilers?

Turns out on master,

--8<---------------cut here---------------start------------->8---
guix size `guix build guile|grep -v debug`
--8<---------------cut here---------------end--------------->8---

returns ~124 MiB, while,

--8<---------------cut here---------------start------------->8---
guix size `guix build --target=3Daarch64-linux-gnu guile|grep -v debug`
--8<---------------cut here---------------end--------------->8---

returns ~523 MiB.

When building the native guile, only the "lib" output of gcc is
kept. When cross-compiling, the whole cross-compiler is dragged down (as
there's only "out" defined for cross-gcc).

That does not explain the sudden increase, but this is still quite
unfortunate :p

Thanks,

Mathieu
