Some Kernel versions include symbols such as "+".
Yocto L4T kernel is an example of this behaviour.
To fix this error all unknown symbols are replaced by an underscore.

Discover other than bool or tristate kconfig options, too. For bool and
tristate the node label is still binary (i.e. set to "true" if the
kconfig option has been enabled). For other kconfig types (e.g. string
or int) the value of the label directly corresponds to the value of the
kconfig flag, e.g. "32", "elf64-x86-64" etc.
Remove the 'selinux' feature source and move the functionality under the
'kernel' feature source. The selinux feature label is changed to
feature.node.kubernetes.io/selinux.enabled
The selinux feature source was rather narrow in scope, and, the sole
feature it advertised naturally falls under the kernel feature source.
This implementation only detects kconfig options ("NO_HZ", "NO_HZ_IDLE",
"NO_HZ_FULL" and "PREEMPT"). The corresponding node labels will be
node.alpha.kubernetes-incubator.io/nfd-kernel-config.<option name>
Currently, only bool and tristate (i.e. '=y' or '=m') kernel config
options are supported. Other kconfig types (e.g. string or int) are
simply ignored. If the kconfig flag is set to '=y' or '=m', the
corresponding node label will be present and it's value will be 'true'.
Add a new 'kernel' feature source, detecting the kernel version. The
kernel version is split into multiple labels in order to make this more
usable in label selectors. Kernel version in the format X.Y.Z-patch will
be presented as
node.alpha.kubernetes-incubator.io/nfd-kernel-version.full=X.Y.Z-patch
node.alpha.kubernetes-incubator.io/nfd-kernel-version.major=X
node.alpha.kubernetes-incubator.io/nfd-kernel-version.minor=Y
node.alpha.kubernetes-incubator.io/nfd-kernel-version.revision=Z
The '.full' label will always be avaiable. The other labels if these
components can be parsed from the kernel version number.
