This breaks running compat_linux as a kernel module:

Aug  4 00:19:19 loggy /netbsd: kobj_checksyms, 974: [compat_linux]: linker error: symbol `compat_43_sys_sethostname' not found
Aug  4 00:19:19 loggy /netbsd: kobj_checksyms, 974: [compat_linux]: linker error: symbol `compat_43_sys_lseek' not found
Aug  4 00:19:19 loggy /netbsd: WARNING: module error: unable to affix module `compat_linux', error 8

I believe paulg made PR kern/51597 for similar issues
