possibly version in the dynamic library, and the optional "<library>"
	names the specific library where the symbol should be found.

	On AIX, the library pattern is slightly different. It must be
	"lib.a/obj.o" with obj.o the member of this library exporting
	this symbol.

	In the <remote>, # or @ can be used to introduce a symbol version.

	Examples:
	//go:cgo_import_dynamic puts
	//go:cgo_import_dynamic puts puts#GLIBC_2.2.5
