If Octave is compiled against a particular BLAS implementation, say "-lopenblas", but is run with LD_PRELOAD=/path/to/libblas.so to force a different BLAS library to be used, the `version -blas` detection still reports OpenBLAS.

This may not be solvable, because both the standard BLAS API as well as OpenBLAS-specific functions are all present in the executable image in this case.
