cmd/dist: add liblink build information
In addition to adding the library, change the way the anames array is created. Previously, it was written to src/cmd/6l/enam.c (and similarly for 5l and 8l) and each of the other tools (6g, 6c, 6a) compiled the 6l/enam.c file in addition to their own sources. Now that there is a library shared by all these programs, move the anames array into that library. To eliminate name conflicts, name the array after the architecture letter: anames5, anames6, anames8. First step to linker cleanup (golang.org/s/go13linker). This CL does not build by itself. It depends on the CLs introducing liblink and changing commands to use it. R=iant CC=golang-dev https://golang.org/cl/35740044
