clang complains:
debuginfod.cxx:354:1: error: unused variable 'apba__'

ARGP_PROGRAM_BUG_ADDRESS_DEF = PACKAGE_BUGREPORT;

../lib/printversion.h:47:21: note: expanded from macro
'ARGP_PROGRAM_BUG_ADDRESS_DEF'
const char *const apba__ __asm ("argp_program_bug_address")

This is as expected: it's used by argp via the
"argp_program_bug_address" name, which is not visible on the C level.
Add __attribute__ ((used)) to make sure that the compiler emits it.
