Comment (by SergeyBiryukov):

 Found an issue with the approach: when using symlinks, `wp-load.php` is
 included from the `src/` directory, which means `ABSPATH` also points to
 `src/`, leading to a warning in the admin:
 > `WARNING: S:\home\wordpress.test\develop\src\wp-
 includes\formatting.php:5434 - readfile(S:\home\wordpress.test\develop\src
 /wp-includes/js/wp-emoji-loader.js): failed to open stream: No such file
 or directory`
 The warning comes from `_print_emoji_detection_script()`:
 {{{
 <?php readfile( ABSPATH . WPINC . '/js/wp-emoji-loader.js' ); ?>
 }}}
 At a glance, these functions are also affected:
 * `rich_edit_exists()`:
 {{{
 $wp_rich_edit_exists = file_exists( ABSPATH . WPINC .
 '/js/tinymce/tinymce.js' );
 }}}
 * `get_post_embed_html()`:
 {{{
 $output .= file_get_contents( ABSPATH . WPINC . '/js/wp-embed.js' );
 }}}
 * `print_embed_scripts()`:
 {{{
 readfile( ABSPATH . WPINC . '/js/wp-embed-template.js' );
 }}}

 `ABSPATH` is set as:
 {{{
 if ( ! defined( 'ABSPATH' ) ) {
         define( 'ABSPATH', dirname( __FILE__ ) . '/' );
 }
 }}}
 Apparently `__FILE__` always resolves symlinks.
 `$_SERVER['SCRIPT_FILENAME']` could help, but it points to the main script
 (e.g. `wp-admin/index.php`), not the currently included file, so `dirname(
 $_SERVER['SCRIPT_FILENAME'] )` does not give the correct path.

 Creating a `wp-config.php` file in the `build/` directory does not help
 either, it's simply ignored.

 Patching `wp-load.php` is the only workaround I can think of at the
 moment:
 {{{
 if ( ! defined( 'ABSPATH' ) ) {
         define( 'ABSPATH', preg_replace( '#src$#', 'build', dirname(
 __FILE__ ) ) . '/' );
 }
 }}}
