Subject: [PATCH] Fix sed -i compatibility on macOS in configure

macOS BSD sed requires an explicit empty string argument after
-i (sed -i '' 'script' file), unlike GNU sed which takes -i
without a suffix argument. Without this fix, BSD sed misinterprets
the sed script as a backup suffix and treats the filename as the
script, causing "unterminated substitute pattern" error.
