Subject: [PATCH v5.15 v2 3/4] lib/Kconfig.debug: Use CONFIG_PAHOLE_VERSION

From: Nathan Chancellor <nathan@...nel.org>

[ Upstream commit 6323c81350b73a4569cf52df85f80273faa64071 ]

Now that CONFIG_PAHOLE_VERSION exists, use it in the definition of
CONFIG_PAHOLE_HAS_SPLIT_BTF and CONFIG_PAHOLE_HAS_BTF_TAG to reduce the
amount of duplication across the tree.
