Keyutils-1.6.1

Not sure why but nfs-utils requires libkeyutils to build with nfsv4 support. Download: keyutils-1.6.1.tar.bz2. This package doesn't have a configure script. Apply a patch to fix the Makefile:

patch -Np1 -i keyutils-1.6.1-bld-20220313.patch

Build the package:

make

We install the required library and header file only:

cp -v libkeyutils.so* /libs/lib/
cp -v libkeyutils.pc /plng/lib/pkgconfig/
cp -v keyutils.h /libs/inc/
