[U-Boot] [PATCH 2/2] kbuild: create symbolic link only for ARM, SPARC, PowerPC, x86

> The symbolic link to SoC/CPU specific header directory is created

> Introduce CONFIG_CREATE_ARCH_SYMLINK to not create unneeded symbolic

'ifdef CONFIG_CREATE_ARCH_SYMLINK' is shorter and maybe easier to read.

But you confused me, I thought this was a kernel patch at first :).
