libcm256cc1-1.1.2-1.1 RPM for x86_64

From OpenSuSE Tumbleweed for x86_64

This is the rewrite in (as much as possible) clean C++ of cm256.
cm256cc is a simple library for erasure codes. From given data it
generates redundant data that can be used to recover the originals.

Changelog

* Sun Aug 30 2026 Martin Pluskal <mpluskal@suse.com>
  - Add cm256cc-fix-pkgconfig-version.patch (gh#f4exb/cm256cc#23):
    PATCH_VERSION was never bumped for 1.1.1 or 1.1.2, so
    libcm256cc.pc still declared 1.1.0 and sdrangel's
    libcm256cc>=1.1.2 check silently disabled its cm256cc plugins.
    Also renames the library file to libcm256cc.so.1.1.2; the
    SONAME is unchanged.
  - Split the shared library out into libcm256cc1 per the shared
    library packaging policy; -devel now requires that instead of the
    main package, which no longer ships anything. libcm256cc1
    obsoletes the old main package, which owned the same library
    paths.
  - Correct License: cm256/gf256 carry the non-endorsement clause so
    they are BSD-3-Clause not BSD-2-Clause, the installed export.h is
    GPL-3.0-only and both public headers include it, and sse2neon.h
    is MIT.
  - Build with -DENABLE_DISTRIBUTION=ON: the default path runs
    try_run() CPU probes on the build host, so the compile flags and
    feature defines depend on which worker picked the job.
  - Add ExclusiveArch: x86_64 aarch64 - upstream has no scalar
    fallback and return()s early without SSSE3/NEON, which built
    nothing and failed %install on ppc64le and s390x. i586 would
    build but SSSE3 is above its baseline, and armv7l needs
    - mfpu=neon, which upstream does not add on this path.
  - Strip upstream's hardcoded /usr/lib install RPATH.
  - Stop installing cm256_rx, cm256_test and cm256_tx; they are
    upstream's unit-test and UDP demo programs, and cm256_tx tripped
    binary-or-shlib-calls-gethostbyname.
  - Run cm256_test as %check.
  - Package the LICENSE file.
  - Drop Group tags and replace deprecated %make_jobs with
    %cmake_build.
