Added OpenBLASConsistentFPCSR

[orkolorko]

We add a package OpenBLASConsistentFPCSR, which is nothing else than OpenBLAS
compiled with the CONSISTENT_FPCSR=1 flag enabled, following issues

#6214
and
JuliaIntervals/IntervalLinearAlgebra.jl#131

This flag controls the fact that, as the thread pool is started, all the threads have the same rounding mode; this flag is not implemented by default since in principle this may affect performance and there are no benchmarks proving the opposite.

The packages is essentially the same as OpenBLAS with two differences:

• we removed the build recipes for 32 bit BLAS (maybe it is not a good idea, but it should be not so much work to add them again)
• we added the flag CONSISTENT_FPCSR=1 at
  https://github.com/orkolorko/Yggdrasil/blob/697e6e7314378e42617c223bbc284780f00270ee/O/OpenBLASConsistentFPCSR/common.jl#L86
• we changed the names of the built packages from "OpenBLAS*" to "OpenBLASConsistentFPCSR*"

I'd only use the latest version, there's little point in building all previous ones.

Ok, even if it seems that this flag is supported on aarch64
OpenMathLib/OpenBLAS@84453b9
the build is failing.

I will work to exclude unsupported platforms.

@giordano the compilation went through without any problems, but I needed to restrict to x86_64

Thanks for your contribution!
