I'd like to propose adding a LINUX-ABI_VERSION pseudo-package that is
provided by each of the Linux kernel packages.
So then a package that requires at least Linux kernel 4.7 (until
recently, -lts was 4.4), can say
requires=('LINUX-ABI_VERSION>=4.7')
conflicts=('LINUX-ABI_VERSION<4.7')
without having to worry about if the user uses linux-libre or
linux-libre-lts or linux-libre-knock-lts or whatever. The "conflicts"
line is important because it handles the case where the user has both
linux-libre and linux-libre-lts installed, but boots to -lts by
default; thus breaking the dependency on the newer kernel.
This can be accomplished by adding "LINUX-ABI_VERSION=${_pkgver%%-*}"
to the provides=() line in the "_package()" function.
