Zig binaries contain absolute paths #79
Description
Follow-up issue to #77.
Zig binaries built in debug mode on MacOS will still contain an absolute path to Bazel's output-base directory, even when the Zig library directory is set to a relative path.
To reproduce:
$ bazel build //zig/tests/simple-binary:binary
$ objdump --syms bazel-bin/zig/tests/simple-binary/binary | grep _bazel
