clapack: new package This package provides BLAS and LAPACK libraries. Though it is common to find implementation of these two libraries in Fortran, this package provides a C-implementation for both, because: - Fortran support has been deprecated in Buildroot since the 2013.11 release; - most of the external toolchains do not provide a Fortran compiler. Often BLAS build-systems build some test programs and run them to generate some source files or adjust some build optimizations, naively assuming they are building the library for the build-machine. This does not play well when cross-compiling. This implementation has this defect too, by building and running a tool generating a header. However, the build-system allows to pass an empty header. So, we have to patch the CMake to build the generator (but never install it) and correctly support building with and without this header provided by the user. Also, some CMake patches are needed to fix the build and install rules.

depends on BR2_PACKAGE_CLAPACK
help
To optimize BLAS library for the hardware, an 'arith.h' header should
be provided.
If empty, the library will not be optimized by the compiler.
In any case an 'arithchk' program is built (but not installed), to be run
on the target to generate this arith.h header.
