[Buildroot] [PATCH v2 5/5] package/xz: convert to cmake build

[Peter Seiderer]

Convert to cmake build with the following autoconf options without
direct equivalent cmake option:

- '--disable-external-sha256'

- '--enable-assembler'

- '--enable-assume-ram=128': hard coded in the CMakeLists.txt file
  1732     target_compile_definitions(xz PRIVATE ASSUME_RAM=128)

- '--enable-scripts' (see [1]: 'CMake: xzdiff, xzgrep, xzless, xzmore, and
  their symlinks are now installed')

- '--enable-symbol-versions': hard coded in the CMakeLists.txt file
  1297     target_compile_definitions(liblzma PRIVATE HAVE_SYMBOL_VERSIONS_LINUX=1)

- '--enable-rpath'

- '--enable-largefile': see CMakeLists.txt
  245 # Check for large file support. It's required on some 32-bit platforms and
  246 # even on 64-bit MinGW-w64 to get 64-bit off_t. This can be forced off on
  247 # the CMake command line if needed: -DLARGE_FILE_SUPPORT=OFF
  248 tuklib_large_file_support(ALL)

- '--enable-unaligned-access=auto': see CMakeLists.txt and cmake/tuklib_integer.cmake
   250 # This is needed by liblzma and xz.
   251 tuklib_integer(ALL)

- '--disable-unsafe-type-punning' see CMakeLists.txt and cmake/tuklib_integer.cmake
   250 # This is needed by liblzma and xz.
   251 tuklib_integer(ALL)

- '--disable-werror'

- '--enable-year2038'
