bug#53484: 29.0.50; Removing libseccomp-dev 2.5.1-1~bpo10+1 allows emacs to compile

[Mark A. Hershberger]

I haven't compiled emacs in a while, but I decided to try it today and
it kept failing on some lines indicating a problem with seccomp.

After removing the debian package in the subject line, compilation was 
successful.

What am I missing without seccomp?

Some of the info from report-bug:
