zig cc -c can only handle one file argument

[hoanga]

zig cc -c handles only one file argument.

gcc and clang both compile and generate object files for each respective file argument given.

also note that zig cc -c handles multiple file arguments differently depending on platform. i.e. on Linux it will only compile the first argument given. On Mac it returns the following type of error message

error: macho does not support linking multiple objects into one

Example gcc run

$ gcc -c c1.c c2.c 
$ ls
c1.c  c1.o  c2.c  c2.o 

Example zig cc run

$ zig cc -c c1.c c2.c 
$ ls 
c1.c  c1.o  c2.c

Zig actually supports this case, taking advantage of the -r flag of LLD to link multiple objects into one. However that only works for WASM and ELF.

Note: This can sometimes surface in e.g. CMake projects if spurious flags like /EHsc /guard:cf end up on the zig cxx command line by accident.
