$ file /gnu/store/qb3jlcb068iv6fz1sqypr12zrcxgi6aq-libpasastro-1.4.2/lib/libpasgetdss.so.1.1
/gnu/store/qb3jlcb068iv6fz1sqypr12zrcxgi6aq-libpasastro-1.4.2/lib/libpasgetdss.so.1.1: ELF 64-bit LSB shared object, UCB RISC-V, RVC, double-float ABI, version 1 (SYSV), dynamically linked, stripped

This package compiles just fine for riscv64 so there's no reason to
limit it to only certain architectures.

(%current-target-system) returns i686-linux-gnu for the first one, so
it'd probably be better to use cond and (target-x86-32?) for the first
one.

I'm not actually convinced you need any of the flags for OS_TARGET or
CPU_TARGET (except perhaps for cross-compiling), does it make a
difference between compiled with or without?
