While building glibc, with ./pre-inst-env guix build -e '((@@ (gnu packages cross-base) cross-gcc) "i686-pc-gnu")' I noticed in the config.log file this:

> COLLECT_GCC=gcc
> COLLECT_LTO_WRAPPER=/gnu/store/z8qifq9172ad17a7mxg9w8jq51axwwqr-gcc-4.8.2/libexec/gcc/x86_64-unknown-linux-gnu/4.8.2/lto-wrapper
> Target: x86_64-unknown-linux-gnu

My question is why isn't it using the cross-gcc? I have cross-gcc as a native input.

In the config.log you can see that although it has included sans-libc gcc it uses the native.

You can see my whole cross-base recipe here :

Any ideas?
