Cannot reproduce this in Docker on centos:8 and fedora:34 with this
Dockerfile (for fedora):

  FROM fedora:34
  RUN dnf install -y \
	  asciidoc \
	  attr \
	  autoconf \
	  automake \
	  diffutils \
	  docbook-xsl \
	  git \
	  gzip \
	  keyutils-libs-devel \
	  libattr-devel \
	  libtool \
	  libxslt \
	  make \
	  openssl \
	  openssl-devel \
	  pkg-config \
	  procps \
	  sudo \
	  vim-common \
	  wget \
	  which
  WORKDIR /src
  COPY . .
  RUN git clean -dxf \
	  && autoreconf -fisv
  RUN ./configure
  RUN make
  RUN make check

Log:

  - openssl pkey -in test-rsa1024.key -out test-rsa1024.pub -pubout
  - openssl req -verbose -new -nodes -utf8 -sha1 -days 10000 -batch -x509 -extensions skid -config test-ca.conf -newkey rsa:1024 -out test-rsa1024_skid.cer -outform DER -keyout test-rsa1024_skid.key
