When compiling with --disable-system there is a harmless yet still
annoying error message at the end of the "configure" step:
sed: can't read *-config-devices.h: No such file or directory
When only building the tools or docs, without any emulator at all,
there is even an additional message about missing *-config-target.h
files.
Fix it by checking whether any of these files are available before
using them.
Fixes: e0447a834d ("configure: Poison all current target-specific #defines")
