The Guix manual makes it sound like the Guix system string can identify
more than just the CPU architecture and kernel.  Specifically, in the
section titled "GNU Distribution", it says the following:

‘armhf-linux’
     ARMv7-A architecture with hard float, Thumb-2 and NEON, using the
     EABI hard-float application binary interface (ABI), and Linux-Libre
     kernel.

‘aarch64-linux’
     little-endian 64-bit ARMv8-A processors, Linux-Libre kernel.  This
     is currently in an experimental stage, with limited support.  *Note
     Contributing::, for how to help!

‘mips64el-linux’
     little-endian 64-bit MIPS processors, specifically the Loongson
     series, n32 ABI, and Linux-Libre kernel.


Is this langugae too specific?
