[PATCH] Makefile: copy SPL_FIT_SOURCE in build directory

[Patrick Delaunay]

Copy the .its source file selected by CONFIG_SPL_FIT_SOURCE
in builddir and in a file named "u-boot.its".

This patch avoid compilation issue when CONFIG_SPL_FIT_SOURCE is used
and KBUILD_OUTPUT is defined, in buildman for example.

Hi,

Problem detected with path proposal:

[V3,3/6] ARM: stm32: Implement board coding on AV96

http://patchwork.ozlabs.org/project/uboot/patch/20200422111814.121060-3-marex@denx.de/

Issue see with:

tools/buildman/buildman -v -V stm32mp15_dhcom_basic stm32mp15_dhcor_basic

Building current source for 2 boards (2 threads, 6 jobs per thread)
       arm:  +   stm32mp15_dhcor_basic

    0    0    2 /2      stm32mp15_dhcom_basic

This error doesn't occur for a local compilation,
as the 2 files exist in  source directory:
"board/dhelectronics/dh_stm32mp1/u-boot-dhcor.its"
"board/dhelectronics/dh_stm32mp1/u-boot-dhcom.its"

But they can't found by buildman in build directory
and the issue is reproduced with "KBUILD_OUTPUT=../build".

With the proposed path the issue is solved.

Regards

Patrick
