I may be doing this wrong, but I'm getting errors from your openblas
build, but not the reference blas package, when I run the following:

$ curl -O

$ gfortran -o sblat2 sblat2.f -lblas
$ rm -f SBLAT2.SUMM
$ curl
https://raw.githubusercontent.com/xianyi/OpenBLAS/develop/test/sblat2.dat

./sblat2

This outputs messages like:
** On entry to SGEMV  parameter number  1 had an illegal value
and so on for the other single-precision level 2 functions in that test.

This does seem to work okay on Linux or an existing i686-w64-mingw32
build.

It fails also on the netlib blas reference so it is not a specific
openblas issue.
It must be something more general like

I think the problem is in the test, changing one flag

both netlib and openblas pass the computational tests.
