Yeap.

I was trying to do something "clever":

diff --git a/meson.build b/meson.build
index 77d2ae87e4..01f3227d62 100644
--- a/meson.build
+++ b/meson.build
@@ -2309,6 +2309,7 @@ config_host_data.set('CONFIG_USBFS', have_linux_user and cc.compiles('''
   int main(void) { return 0; }'''))
 
 have_keyring = get_option('keyring') \
+  .require(keyutils.found(), error_message: 'keyring requires keyutils libraries') \
   .require(targetos == 'linux', error_message: 'keyring is only available on Linux') \
   .require(cc.compiles('''
     #include <errno.h>
(test-secret *)$ 

But it is only the test what requires CONFIG_KEYUTILS,
crypto/secret_keyring.c don't needs it, so we need to do both ifdefs.
