to the gcc invocation. If we pass a flag like -Wl, then gcc will call the linker unless it can figure out that it has to do something else (e.g., because of a "-c" flag). So if no non-flag arguments are given, don't pass any linker flags. This catches cases like "gcc" (should just print "gcc: no input files") and "gcc -v" (should print the version). svn path=/nixpkgs/trunk/; revision=8644
