BUG: "BLAS alone" detection on Windows failing with 32 bit pseudo relocation out of range

[maresb]

Describe the issue:

Reported in https://github.com/pymc-devs/pytensor/pull/1667#issuecomment-3447731251

If MKL detection fails, then we see the following new error:

Mingw-w64 runtime failure: 32 bit pseudo relocation at 00007FF6E32314BC out of range, targeting 00007FF985A31600, yielding the value 00000002A2800140.

This comes from "Checking Lapack + blas" and "Checking blas alone":

Reproducable code example:

import logging
logger = logging.getLogger("pytensor.link.c.cmodule")
logger.setLevel(logging.DEBUG)
import pytensor
pytensor.config.blas__ldflags
