Summary: We're trying to use the --config options to pass distro specific options for Fedora via the CFLAGS variable. However, some projects end up using the CFLAGS variable multiple times in their command line, which leads to an error when --config is used. This patch resolves this issue by allowing more than one --config option on the command line as long as the file names are the same.
