A TLS slot is reserved by _rt0_.*_plan9 as an automatic and its address (which is static on Plan 9) is saved in the global _privates symbol. The startup linkage now is exactly like that from Plan 9 libc, and the way we access g is exactly as if we'd have used privalloc(2). Aside from making the code more standard, this change drastically simplifies it, both for 386 and for amd64, and makes the Plan 9 code in liblink common for both 386 and amd64. The amd64 runtime code was cleared of nxm assumptions, and now runs on the standard Plan 9 kernel. Note handling fixes will follow in a separate CL.
