[bug#47006] [PATCH v2 0/1] gnu: Add zig.

[Léo Le Bouter]

I attempted to add tests, Zig has an unconventional way of requiring tests to be
run after installation so I added a 'check phase after the 'install phase which
works but then after lots of tests succeeded there is a FileNotFound error cause
by some 'test' binary failing to run.

I found out by running:

$ ./pre-inst-env guix build --keep-failed zig
$ cd /tmp/guix-build-zig-0.7.1.drv-0/source
$ env -i $(which bash)
$ source ../environment-variables
$ /run/current-system/profile/bin/strace -f -e trace=file 
/gnu/store/1cmjgdiim452bqkzgp53d0kw4fi4gfar-zig-0.7.1/bin/zig build test

 ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, 
interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.0.0, with debug_info, 
not stripped

The issue here is that this binary should work fine already according to the
output of ldd and file. We would need a way to get verbose debugging errors of
execve somehow.
