This is the error I get
plutil -convert binary1 -o /tmp/WebKit.dst/System/Library/LaunchDaemons/com.apple.webkit.webpushd.plist /Users/svillar/WebKit/Source/WebKit/webpushd/com.apple.webkit.webpushd.plist
/tmp/WebKit.dst/System/Library/LaunchDaemons/com.apple.webkit.webpushd.plist: Permission denied
** BUILD FAILED **
A collegue of mine owns the files the build is trying to access to in the /tmp directory. As I don't have enough permissions to write it the build fails.
Without actually looking into what creates this file, I expect that the fix will be similar to that in bug 132053.
