Subject: SBCL enomem on 686
Date: Tue, 13 Feb 2024 07:22:31 -0900

Hi, I was trying to run SBCL on an older 32-bit laptop, using guix on foreign distro. When I launch SBCL, the REPL dies immediately with this error:

```
os_alloc_gc_space(1,0x9000000,3221225472) failed with ENOMEM
fatal error encountered in SBCL pid 4657 tid 4657:
Can't allocate 0xc0000000 bytes for space 1
```

However, the program does work if I pass in a --dynamic-space-size argument when I launch sbcl. E.g.

```
sbcl --dynamic-space-size 2000
```

So, it seems like some allocation value or define is not being set correctly in the build for 686. SBCL manual only says:

```
‘--dynamic-space-size MEGABYTES’
     Size of the dynamic space reserved on startup in megabytes.
     Default value is platform dependent.
```

My system information:
