route methods are executed during build

[joshuabaker]

Link to the code that reproduces this issue

https://github.com/joshuabaker/nextjs-issue-route-get-during-build

To Reproduce

Create a route.js or route.ts file with a GET method.

Insert a fetch call.

Example

import {NextResponse} from 'next/server';

export async function GET(request) {
    try {
        const response = await fetch('https://www.example.com', {cache: 'no-store'});
        const html = await response.text();
        console.log(html);

        const url = new URL(request.url);
        const {searchParams} = url;
        const q = searchParams.get('q') || 'foobar';
        console.log(q);

        return NextResponse.json({q});
    } catch (e) {
        console.log(e);
        return NextResponse.json({e});
    }
}

Current vs. Expected behavior

The build often fails as the method is executed, meaning certain env vars, target paths, etc. are not present.
