* __v2.27.0 (2023-05-30)__

  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).
