[U-Boot] [PATCH v2] Let source cross-reference targets follow symbolic links

[hkronsto at frequentis.com]

From: Horst Kronstorfer <hkronsto at frequentis.com>

Without telling 'find' to follow symbolic links, files under include/asm
and arch/$(ARCH)/include/asm/arch are not added to the indexing file list.

Signed-off-by: Horst Kronstorfer <hkronsto at frequentis.com>

Changes for v2:
    - Apply this change to all source cross-reference targets
