Subject: [PATCH] Makefile: Add missing quotes around sort --field-separator
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Busybox sort does not handle --field-separator== , replace this
with --field-separator='=' for maximum compatibility.

Fixes: cc5a490cf465 ("Makefile: Sort u-boot-initial-env output")
