bug#40071: Cross-compiled package closure size.

bug#40071: Cross-compiled package closure size.

[Mathieu Othacehe]

Hello,

After applying the patch proposed here[1], the closure of cross-compiled
"hello" still contains unwanted packages.

The native glibc, gcc-lib and one of the two bash-static packages should
be removed.

The gcc-cross-sans-libc-aarch64-linux-gnu-7.5.0-lib may also be removed.

Ideally, we would have a closure similar to the native one, with
something like this:

--8<---------------cut here---------------start------------->8---
/gnu/store/vm2gaw5jk1zr1x9qzj4z52qjxvrh0nk9-glibc-cross-aarch64-linux-gnu-2.31   158.9    71.4  38.2%

Well, using Guix 729ce5f, the situation is sadly similar,

What is the next step to tackle that?
