Not completely true: the "linux custom path" feature is not replaced by
BR2_GLOBAL_PATCH_DIR. If one wants to get the same functionality, i.e
telling Buildroot to use the Linux kernel source code from an available
local directory, then the only solution is to use LINUX_OVERRIDE_SRCDIR.

Best regards,
