I have appended below the occurrences in config.log for seccomp.h. (Do
you want me to attach the whole config.log in a second email?) The only
other mentions are multiple lines of the form

  5090:| #define HAVE_LINUX_SECCOMP_H 1

ending with

  27758:ac_cv_header_linux_seccomp_h=yes
  27771:ac_cv_header_seccomp_h=yes
  29332:#define HAVE_LINUX_SECCOMP_H 1

Hope this helps.
