Bun build fail to import implicit '.node' files when target is set to node

[Fadoli]

What version of Bun is running?

1.1.38+bf2f153f5

What platform is your computer?

Linux 6.11.5-amd64 x86_64 unknown

What steps can reproduce the bug?

Building with a target set to "node" with one of the JS file implicitly importing a .node addon, like for example krb5.

require('../build/Release/krb5');

What is the expected behavior?

When building for the bun target, the build is successfull.

The target node should behave the same way.

What do you see instead?

When building and targeting node the following error is emited :

❱ bun ./build.js  
140 |         format: 'cjs',
141 |         target: 'node',
142 |         external: []
143 |     }).then((output) => {
144 |         if (!output.success) {
145 |             throw new Error(`Failed backend bun build :\n${output.logs.join('\n')}`);
                        ^
error: Failed backend bun build :
ResolveMessage: Could not resolve: "../build/Release/krb5"

Would it be possible to provide your build.js file?

Yes but it's actually not required, the trigger is selecting node as a target.

Here is minimal files to reproduce the issue with the build file :

build.js :

const Bun = require('bun');

async function build() {
    await Bun.build({
        entrypoints: ['test.js'],
        outDir: './bun-build',
        format: 'cjs',
        target: 'node',
        external: []
    }).then((output) => {
        if (!output.success) {
            throw new Error(`Failed backend bun build :\n${output.logs.join('\n')}`);
        } else {
            console.log('Bun backend build successful');
        }
    });
}
build();

test.js :

const krb5 = require('krb5');

It happens when running bun build --target node ./test.js as well, with bun build --target bun ./test.js working as expected
