v2.27.0

For Linux kernel version: 6.3

Changes of existing tools:

• s390-tools cross-compile and non-s390x support:
  • pkg-config is now mandatory for the build process
  • Add PKG_CONFIG Makefile variable to select pkg-config program;
    default pkg-config or $(CROSS_COMPILE)pkg-config if
    CROSS_COMPILE is set
  • Rename Makefile variable ARCH to HOST_ARCH. HOST_ARCH is the
    architecture that will run the produced (executable) objects
  • Add the Makefile variable BUILD_ARCH. BUILD_ARCH is the
    architecture of the build system. For each Makefile variable like
    CC, LINK, CPP, ... there is a suffixed version of it - e.g.
    CC_FOR_BUILD. This is useful for cross compiling, and this naming
    convention is very similar to the Meson convention (see
    https://mesonbuild.com/Reference-tables.html#environment-variables-per-machine).
