When using the GNU toolchain a warning is printed about an executible
stack:
 /usr/lib64/gcc/.../x86_64-suse-linux/bin/ld: warning: /tmp/ccyG3xBB.o: missing .note.GNU-stack section implies executable stack
[   15s] /usr/lib64/gcc/.../x86_64-suse-linux/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
to prevent this warning, add:
    ```

On z-series, the current version of the GNU toolchain produces warnings
such as:
```
/usr/lib64/gcc/[...]/s390x-suse-linux/bin/ld: warning: ztrmm_kernel_RC_Z14.o: missing .note.GNU-stack section implies
executable stack
/usr/lib64/[...]/s390x-suse-linux/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
```
To prevent this message and make sure we are future proof, add
```
	.section        .note.GNU-stack,"",@progbits
```
Also add the `.size` bit to give the asm defined functions a proper size
in the symbol table.

Fix misinterpretation of NO_LAPACK=0 and SPMV settings in CMake builds

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`.
