Subject: configure: rework setting of privops macros
X-Git-Tag: 2.3-pre1~66
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fedc605956a0bfedb10b2e218308c38d692268a5;p=thirdparty%2Fchrony.git

configure: rework setting of privops macros

Prepare a list of required privileged operations first and from that
define the PRIVOPS macros. This will reduce the amount of code that will
be needed when the privileged helper is used on other platforms.
