unable to handle compilation, expected exactly one compiler job in ...

Hi,
I'm having trouble getting autowrap to work for me. I'm using docker based on the c2ffi CI script (see below). I do

(setq autowrap::*trace-c2ffi* t)
(autowrap:c-include "/root/quicklisp/dists/quicklisp/software/cl-autowrap-20210411-git/t/test.h")

and get output

; Invoking: c2ffi /root/quicklisp/dists/quicklisp/software/cl-autowrap-20210411-git/t/test.h -D null -M /tmp/tmp9KKTJMYV.tmp -A x86_64-pc-linux-gnu
; Invoking: c2ffi /tmp/tmpJU0JWO19.tmp -o /root/quicklisp/dists/quicklisp/software/cl-autowrap-20210411-git/test.x86_64-pc-linux-gnu.spec -A x86_64-pc-linux-gnu

               "-A" "x86_64-pc-linux-gnu")
 exited with error code 1

When I run the same command directly in a shell I get

warning: /tmp/tmpJU0JWO19.tmp: 'linker' input unused
error: unable to handle compilation, expected exactly one compiler job in '/tmp/tmpJU0JWO19.tmp'

The tmp file contents:

#include "/root/quicklisp/dists/quicklisp/software/cl-autowrap-20210411-git/t/test.h"
#include "/tmp/tmp9KKTJMYV.tmp"

The generated .spec file is empty as is /tmp/tmp9KKTJMYV.tmp. Something I'm doing wrong?
