I think this condition should go *inside* the
($(BR2_LINUX_KERNEL_CUSTOM_TARBALL),y) condition. Indeed with your
current situation, if by any chance I have a Git tag such as
this-is-a-rc-kernel, then it will match your condition, and ignore the
Git repository address.

So I really think we want to test the -rc case inside the
($(BR2_LINUX_KERNEL_CUSTOM_TARBALL),y) condition, such as:

ifeq ($(BR2_LINUX_KERNEL_CUSTOM_TARBALL),y)
ifneq ($(findstring -rc,$(LINUX_VERSION)),)
LINUX_SITE = https://git.kernel.org/torvalds/t
else
...
endif
endif # tarball

Also, please use "=" to assign variables, not ":=".

Best regards,

Thomas
