[Buildroot] [PATCH] support/testing: TestPythonPy3SciPy: needs a toolchain with Fortran support

[Romain Naour via buildroot]

Switch to the Bootlin bleeding-edge toolchain since stable toolchain no
longer provide Fortran support since 2024.05-1 release [1].

The Fortran support is now optional in toolchain-builder tool and
only enabled for bleeding-edge toolchains [2].

Applied to master, thanks. Of course, we need to understand why the
Bootlin stable toolchains lost Fortran support, but that's another
story :-)
