Subject: cross-gcc-toolchain for riscv64 doesn't search crt1.o properly
Date: Sun, 25 Feb 2024 21:07:17 +0100

Hi,

I made this package:

```
(define-module (cross)
  #:use-module (guix packages)
  #:use-module (guix gexp)
  #:use-module (gnu packages cross-base))

(define-public gcc-cross-riscv64-linux-gnu-toolchain
               (cross-gcc-toolchain "riscv64-linux-gnu"))
```

And used in in the session you can read in the bottom of this email.

During the session, the `crt1.o` file is not found, and the 
`riscv64-linux-gnu-gcc -v whatever.c` call shows `crt1.o` is passed to 
the compiler using only the name, while in `gcc-toolchain` it's passed 
using the full path to the libc.

This looks like the `cross-gcc-toolchain` is missing some configuration 
for proper usage in a guix shell.

Best,
Ekaitz


The session I that explains the behavior:
