Pulseaudio provides an implementation of memfd_create which

Since we claim to support older versions of
LFS (and 2.27 is a very recent change) I think we'd better use the
upstream patch - builds with autoreconf -fiv && intoolize -f.

This was only suppsoed to be a dry run to find the bugs in my own
buildscript changes.  Aren't toolchain changes a pleasure.

I thought I fixed that, but upon research, it never made it into the book.

Short answer:

sed -i '/int memfd_create/,+2 d' src/pulsecore/memfd-wrappers.h
