Hi,

(CC: Helmut and Santiago because the failure looks similar to ~2 of the 
FTBFS one-liners from Santiago on June 9th. Thought it might be 
unrelated - this build seems to be based on autotools in case it matters)

The armci-mpi package has an autopkgtest called "test-armci" that fail 
due to a compilation error:

>  57s /bin/bash ./libtool  --tag=CC   --mode=compile x86_64-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I./src  -I./src -Wdate-time -D_FORTIFY_SOURCE=2  -I/usr/include -c -o src/buffer.lo src/buffer.c
>  57s libtool: compile:  x86_64-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I./src -I./src -Wdate-time -D_FORTIFY_SOURCE=2 -I/usr/include -c src/buffer.c -o src/buffer.o

This was triggered after an upload of `debhelper`. I am unsure whether 
the debhelper upload caused this problem or just happened to be the 
first trigger after the problem occurred elsewhere.

Best regards,
