Clean removes object files from package source directories.
The go command builds most objects in a temporary directory,
so go clean is mainly concerned with object files left by other
tools or by manual invocations of go build.

If a package argument is given or the -i or -r flag is set,
clean removes the following files from each of the

	MFiles            []string `json:",omitempty"` // .m source files
	HFiles            []string `json:",omitempty"` // .h, .hh, .hpp and .hxx source files
	FFiles            []string `json:",omitempty"` // .f, .F, .for and .f90 Fortran source files
	SFiles            []string `json:",omitempty"` // .s source files
	SwigFiles         []string `json:",omitempty"` // .swig files
	SwigCXXFiles      []string `json:",omitempty"` // .swigcxx files

When the Go tool sees that one or more Go files use the special import
"C", it will look for other non-Go files in the directory and compile
them as part of the Go package. Any .c, .s, .S or .sx files will be
compiled with the C compiler. Any .cc, .cpp, or .cxx files will be
compiled with the C++ compiler. Any .f, .F, .for or .f90 files will be
compiled with the fortran compiler. Any .h, .hh, .hpp, or .hxx files will
