configs/imx6sabre: Create distinct pre-processed mkimage config files

Commit 0c4bccf9e882 ("configs/imxsabre: Fix U-Boot parallel build issue")
tried to fix the parallel build issue, but the real fix was developed
later by Trent Piepho later, so add such commit to fix Buildroot
build failures on rel_imx_4.9.x_1.0.0_ga NXP branch.

+Subject: [PATCH] imx: Create distinct pre-processed mkimage config files
+
+Each imx image is created by a separate sub-make and during this process
+the mkimage config file is run though cpp.
+
+The cpp output is to the same file no matter what imx image is being
+created.
+
+This means if two imx images are generated in parallel they will attempt
+to independently produce the same pre-processed mkimage config file at
+the same time.
+
+Avoid the problem by making the pre-processed config file name unique
+based on the imx image it will be used in.  This way each image will
+create a unique config file and they won't clobber each other when run
+in parallel.
+
+This should fixed the build bug referenced in b5b0e4e3 ("imximage:
+Remove failure when no IVT offset is found").

-Subject: [PATCH] imximage: Remove failure when no IVT offset is found
-
-Sometimes imximage throws the following error:
-
-  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
-  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
-  MKIMAGE u-boot-dtb.imx
-Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp
-arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed
-
-Later on, when running mkimage for the u-boot.imx it will succeed in
-finding the IVT offset.
-
-Looks like some race condition happening during parallel build when
-processing mkimage for u-boot-dtb.imx and u-boot.imx.
-
-A proper fix still needs to be implemented, but as a workaround let's
-remove the error when the IVT offset is not found.
-
-It is useful to have such message, especially during bring-up phase,
-but the build error that it causes is severe, so better avoid the
-build error for now.
-
-The error checking can be re-implemented later when we have a proper
-fix.
