The problem is as per official OpenBLAS docs
(https://github.com/xianyi/OpenBLAS/blob/c3f2a3c0ca8d4a3700f81f176dd3f1bc08cff3dd/docs/distributing.md?plain=1#L79)
that some applications expect a `libopenblas64_.so` name, but Guix
chooses it's custom `-ilp64`. This messes up with Julia for example. If
the suffix `-ilp64` is needed, there also needs to be a `64_`
suffix. Otherwise some apps inexplicably fail on a wrongly named file.
