Subject: [MINIOS PATCH] build: prepend OBJ_DIR to linker script
Date: Tue, 13 Dec 2016 15:02:02 +0000	[thread overview]
Message-ID: <1481641322-24257-1-git-send-email-wei.liu2@citrix.com> (raw)

After 5623e2d2 ("x86: use unified linker script") the linker script for
x86 build is generated. But the special rule to generate linker script
doesn't have OBJ_DIR prepended so in parallel build the same file is
written multiple times. This is racy and would cause parallel build to
fail.

Fix this by prepending OBJ_DIR to the path of linker script. Change
other variables where necessary.
