  Link, typically invoked as ``go tool link,'' reads the Go archive or object
  for a package main, along with its dependencies, and combines them
  into an executable binary.
  Command Line
  	go tool link [flags] main.a
  	-B note
  		Add an ELF_NT_GNU_BUILD_ID note when using ELF.
  		The value should start with 0x and be an even number of hex digits.
  	-D address
  		Set data segment address.
  	-E entry
  		Set entry symbol name.
  	-H type
  		Set executable format type.
  		The default format is inferred from GOOS and GOARCH.
  		On Windows, -H windowsgui writes a "GUI binary" instead of a "console binary."
  	-I interpreter
  		Set the ELF dynamic linker to use.
  	-L dir1 -L dir2
  		Search for imported packages in dir1, dir2, etc,
  		after consulting $GOROOT/pkg/$GOOS_$GOARCH.
  	-R quantum
  		Set address rounding quantum.
  	-T address
  		Set text segment address.
  		Print linker version and exit.
  	-X importpath.name=value
  		Set the value of the string variable in importpath named name to value.
  		This is only effective if the variable is declared in the source code either uninitialized
  		or initialized to a constant string expression. -X will not work if the initializer makes
  		a function call or refers to other variables.
  		Note that before Go 1.5 this option took two separate arguments.
  	-buildmode mode
  		Set build mode (default exe).
  	-cpuprofile file
  		Write CPU profile to file.
  		Disable generation of dynamic executables.
  		The emitted code is the same in either case; the option
  		controls only whether a dynamic header is included.
  		The dynamic header is on by default, even without any
  		references to dynamic libraries, because many common
  		system tools now assume the presence of the header.
  	-extar ar
  		Set the external archive program (default "ar").
  		Used only for -buildmode=c-archive.
  	-extld linker
  		Set the external linker (default "clang" or "gcc").
  	-extldflags flags
  		Set space-separated flags to pass to the external linker.
  		Ignore version mismatch in the linked archives.
  		Disable Go package data checks.
  	-installsuffix suffix
  		Look for packages in $GOROOT/pkg/$GOOS_$GOARCH_suffix
  		instead of $GOROOT/pkg/$GOOS_$GOARCH.
  	-libgcc file
  		Set name of compiler support library.
  		This is only used in internal link mode.
  		If not set, default value comes from running the compiler,
  		which may be set by the -extld option.
  		Set to "none" to use no support library.
  	-linkmode mode
  		Set link mode (internal, external, auto).
  		This sets the linking mode as described in cmd/cgo/doc.go.
  		Link against installed Go shared libraries (experimental).
  	-memprofile file
  		Write memory profile to file.
  	-memprofilerate rate
  		Set runtime.MemProfileRate to rate.
  		Link with C/C++ memory sanitizer support.
  	-o file
  		Write output to file (default a.out, or a.out.exe on Windows).
  	-pluginpath path
  		The path name used to prefix exported plugin symbols.
  	-r dir1:dir2:...
  		Set the ELF dynamic linker search path.
  		Link with race detection libraries.
  		Omit the symbol table and debug information.
  		Generated shared object (implies -linkmode external; experimental).
  	-tmpdir dir
  		Write temporary files to dir.
  		Temporary files are only used in external linking mode.
  		Print trace of linker operations.
  		Omit the DWARF symbol table.
