conftest.c (based configure's cross compilation test)

This runs Ok when compiled with "-O2 -g -gdwarf-4", but fails with Windows
error code 193 aka "Exec format error" when compiled with "-O2 -g -gdwarf-5=
".
The error is reproducible with a x86_64-w64-mingw32 cross (just transfer the
EXEs to Windows for execution).

Compiling with -S shows differences in several .debug sections.=
