I propose to tweak openblas-ilp64.  Currently it looks like:

--8<---------------cut here---------------start------------->8---
$ tree $(guix build openblas-ilp64)/lib
/gnu/store/v6z5ykkjfzbc72x1x900xflspqc5wd5r-openblas-ilp64-0.3.20/lib
├── cmake
│   └── openblas
│       ├── OpenBLASConfig.cmake
│       └── OpenBLASConfigVersion.cmake
├── libopenblas_ilp64p-r0.3.20.so
├── libopenblas_ilp64.so -> libopenblas_ilp64p-r0.3.20.so
├── libopenblas_ilp64.so.0 -> libopenblas_ilp64p-r0.3.20.so
└── pkgconfig
    └── openblas.pc
--8<---------------cut here---------------end--------------->8---

which is inconsistent with pkgconfig as you noticed above.  Therefore, I
am proposing the addition of a symlink of libopenblas_ilp64p.so to
libopenblas.so.  For instance this attached patch.
