ORS=" " adds a blank to the name of the include file.
Some shells (e.g. dash) don't accept input redirection
(tr -d '\r' < $f) when $f ends with a blank, so they
print an error message instead of reading pci.mak.
This is a non-fatal error because pci.mak does not
contain an include line. It was introduced by commit
5d6b423c5cd6f9dfac30959ff1d5c088996719c3.
Using printf avoids adding a blank and is also supported
by older awk versions (this solution was suggested by
Paolo Bonzini, thank you).

QEMU source code with CRLF line endings
which is quite common on windows hosts
fails with current make_device_config.sh.
The awk script gets the name of the included
file with \r, so instead of pci.mak it will
search for pci.mak\r which of course does
not work.
Fix this by removing any \r.
v2:
Avoid using sub() and \r with awk because they are unsupported
on some platforms. Use tr to remove \r. This new solution
improves portability and was suggested by Paolo Bonzini.

Terminate make_device_config.sh if the awk command fails.
Typically this means a missing file.
