Our cc-wrapper is broken whenever the '-x' flag is used: 'gcc -x c foo.c -o bar' doesn't work the same way as 'gcc foo.c -o bar' does. (Try both with NIX_DEBUG=1.) What happens is that passing '-x' causes linker-related flags (such as -Wl,-dynamic-linker) not to be added, just like if '-c' is passed. The bug happens outside the multiple-outputs branch as well, but it doesn't break imake there. It only breaks in multiple-outputs because linking without -Wl,-dynamic-linker produces a binary with an invalid ELF interpreter path. (Which arguably, is a bug in its own.)
