Subject: configure: improve check for timestamping options
X-Git-Tag: 3.3-pre1~40
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da60629201ff7a781bbf06107bb5f65afa919533;p=thirdparty%2Fchrony.git

configure: improve check for timestamping options

The socket.h header provided by musl doesn't seem to include the kernel
headers and is missing SCM_TIMESTAMPING_PKTINFO, which causes the
Linux-specific code in chrony to fail to build.
