Subject: build system: Define which version of libkvm has been checked for.
X-Git-Tag: collectd-4.3.4~16
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=aac435a16a547dd0a7621d0cda75b2918b24b515;p=collectd.git

build system: Define which version of libkvm has been checked for.

The used `kvm_getswapinfo' is apparently an extension not all versions of the
kvm library support.
