mv cmd/new5l cmd/5l and so on.

Minimal changes to cmd/dist and cmd/go to keep things building.
More can be deleted in followup CLs.

-/*
-
-Ld is the portable code for a modified version of the Plan 9 linker.  The original is documented at
-
-	http://plan9.bell-labs.com/magic/man2html/1/8l
-
-It reads object files (.5, .6, .8, .9 files) and writes a binary named for the
-architecture (5.out, 6.out, 8.out, 9.out) by default (if $GOOS is windows, a .exe suffix
-will be appended).
-
-Major changes include:
-	- support for ELF, Mach-O and PE binary files
-	- support for segmented stacks (this feature is implemented here, not in the compilers).
-
-Original options are listed on the manual page linked above.
-
-Usage:
-	go tool 6l [flags] mainObj
-Substitute 6l with 5l, 8l or 9l as appropriate.
-
-Options new in this version:
-
-	-d
-		Elide the dynamic linking header.  With this option, the binary
-		is statically linked and does not refer to a dynamic linker.  Without this option
-		(the default), the binary's contents are identical but it is loaded with a dynamic
-		linker. This flag cannot be used when $GOOS is windows.
-	-H darwin     (only in 6l/8l)
-		Write Apple Mach-O binaries (default when $GOOS is darwin)
-	-H dragonfly  (only in 6l/8l)
-		Write DragonFly ELF binaries (default when $GOOS is dragonfly)
-	-H linux
-		Write Linux ELF binaries (default when $GOOS is linux)
-	-H freebsd
-		Write FreeBSD ELF binaries (default when $GOOS is freebsd)
-	-H netbsd
-		Write NetBSD ELF binaries (default when $GOOS is netbsd)
-	-H openbsd    (only in 6l/8l)
-		Write OpenBSD ELF binaries (default when $GOOS is openbsd)
-	-H solaris    (only in 6l)
-		Write Solaris ELF binaries (default when $GOOS is solaris)
-	-H windows    (only in 6l/8l)
-		Write Windows PE32+ Console binaries (default when $GOOS is windows)
-	-H windowsgui (only in 6l/8l)
-		Write Windows PE32+ GUI binaries
-	-I interpreter
-		Set the ELF dynamic linker to use.
-	-L dir1 -L dir2
-		Search for libraries (package files) in dir1, dir2, etc.
-		The default is the single location $GOROOT/pkg/$GOOS_$GOARCH.
-	-r dir1:dir2:...
-		Set the dynamic linker search path when using ELF.
-	-s
-		Omit the symbol table and debug information.
-	-V
-		Print the linker version.
-	-w
-		Omit the DWARF symbol table.
-	-X symbol value
-		Set the value of a string variable. The symbol name
-		should be of the form importpath.name, as displayed
-		in the symbol table printed by "go tool nm".
-	-race
-		Link with race detection libraries.
-	-B value
-		Add a NT_GNU_BUILD_ID note when using ELF.  The value
-		should start with 0x and be an even number of hex digits.
-	-Z
-		Zero stack on function entry. This is expensive but it might
-		be useful in cases where you are suffering from false positives
-		during garbage collection and are willing to trade the CPU time
-		for getting rid of the false positives.
-		NOTE: it only eliminates false positives caused by other function
-		calls, not false positives caused by dead temporaries stored in
-		the current function call.
-	-linkmode argument
-		Set the linkmode.  The argument must be one of
-		internal, external, or auto.  The default is auto.
-		This sets the linking mode as described in
-		../cgo/doc.go.
-	-tmpdir dir
-		Set the location to use for any temporary files.  The
-		default is a newly created directory that is removed
-		after the linker completes.  Temporary files are only
-		used in external linking mode.
-	-extld name
-		Set the name of the external linker to use in external
-		linking mode.  The default is "gcc".
-	-extldflags flags
-		Set space-separated trailing flags to pass to the
-		external linker in external linking mode.  The default
-		is to not pass any additional trailing flags.
