zig env: lib_dir and std_dir are relative paths in stage2, stage3 and stage4

[perillo]

I built the compiler following the newly updated https://github.com/ziglang/zig/wiki/Contributing.

Unlike the zig compiler from https://ziglang.org/download/, lib_dir and std_dir are always relative paths.

$ ~/src/contrib/zig/github.com/perillo/zig/build/stage4/bin/zig env

{
 "zig_exe": "/home/manlio/src/contrib/zig/github.com/perillo/zig/build/stage4/bin/zig",
 "lib_dir": "src/contrib/zig/github.com/perillo/zig/lib",
 "std_dir": "src/contrib/zig/github.com/perillo/zig/lib/std",
 "global_cache_dir": "/home/manlio/.cache/zig",
 "version": "0.11.0-dev.6172+59d9afcb5",
 "target": "x86_64-linux.6.1.7...6.1.7-gnu.2.36"
}

Maybe the problem is caused by DZIG_NO_LIB=ON and -Dno-lib ?
