+Subject: [PATCH] configure.ac: make --disable-seccomp work
+
+The first branch ("[action-if-given]") is taken even if --disable-seccomp
+is passed. So, in that branch, check whether the user disabled it or not.
+
+Without this, we'd get a failure when seccomp is detected but we want
+to disable it:
+```
+./configure --disable-seccomp
+[...]
+checking for library containing clock_gettime... none required
+configure: error: --enable-seccomp given but seccomp libraries not present
+```
