Problems with windows and LIBNAMEPREFIX

[mattip]

#4485 went a long way to adding a prefix and suffix to the lib name, and allowing FIXED_LIBNAME=1, thanks.

But ... there is a difference between windows and posix. I used HEAD in MacPython/openblas-libs#141. On non-windows, I need to define both SYMBOLPREFIX=scipy_ and LIBNAMEPREFIX=scipy_ (and correspondingly, SYMBOLSUFFIX=64_ and LIBNAMESUFFIX=64_ when using INTERFACE64=1). But on windows, I must only define SYMBOLPREFIX=scipy_. Defining LIBNAMEPREFIX=scipy_ as well results in libscipy_scipy_openblas...

I currently worked around this since the CI runs are separate, but I wonder if this is intentional? The "offending" uses are in Makefile.system.

Thought I had tracked down all sources of stuttering... will try to fix this tomorrow.

Hmm. Actually it should be the same on non-Windows systems with the current solution - or are you building with gmake in one case and cmake in the other ?
