hmeiland d6e64e8032 U74 target: add CMake build support 
Mirror the RISCV64_GENERIC target blocks for U74 in cmake/prebuild.cmake
(cache defines: 32 KiB L1D / 2 MiB L2, 64 B lines, matching getarch),
cmake/system.cmake and cmake/cc.cmake
(-march=rv64imafdc_zba_zbb -mabi=lp64d -mtune=sifive-u74), so
'cmake -DTARGET=U74' builds alongside the Makefile path.

Verified on a VisionFive 2: configure recognizes the target and a full
'cmake --build' produces libopenblas.a with the U74 march/mtune flags
applied to the kernel objects (0 errors).

Jameson NashandClaude Opus 4.5 4026d7ba7c Fix LIBNAMESUFFIX handling in CMake and update documentation 
- Fix cmake/system.cmake: LIBPREFIX was incorrectly overwritten when
  LIBNAMESUFFIX was defined, losing both "lib" prefix and "openblas"
- Fix Makefile.rule docs: typo used LIBNAMESUFFIX instead of LIBNAMEPREFIX
- Fix Makefile.rule docs: removed misleading underscores from examples
- Fix docs/build_system.md: removed incorrect claim about automatic
  underscore separator

The implementation does not add an underscore before the suffix - users
who want a separator should include it in their LIBNAMESUFFIX value
(e.g., LIBNAMESUFFIX=_omp).

Ruiyang Wu 02fd1df10b CMake: Pass OpenMP compiler and linker flags through CMake targets 
Using `OpenMP::OpenMP_LANG` targets for CMake is less error-prone than
passing the compiler and linker flags manually. Furthermore, it allows
the user to customize those flags by setting `OpenMP_LANG_FLAGS`,
`OpenMP_LANG_LIB_NAMES`, and `OpenMP_omp_LIBRARY`.
