9e7f3a46d3 restore the old algorithm. the new one is more memory efficient in large cases
but too slow across the board.

586d9d5a19 use $(shell uname) instead of $GOOS when
deciding what the host process support is.
this makes a cross-compiling (e.g., GOOS=nacl) build
still generate valid host debugger binaries.

required for nacl and may be nicer for ffi,
because %gs is the standard register for thread-local storage.

fed4770685 step 2 of the great buffer shift.
make strings.Buffer handle strings and bytes with comparable efficiency.
if ok, next step will be to move this code to bytes.Buffer and terminate
strings.Buffer's short happy life.

4a4ec23870 8l: step toward native client.
- ELF header bits and addresses
  - do not let instructions span 32-byte boundary
  - align CALLs so return is to 32-byte boundary
  - align indirect jump targets to 32-byte boundary
    (only possible indirect jumps are function entries)

still to do:
  - replace indirect jump, indirect call, and ret with
    nacl-approved instruction sequences
  - switch to GS segment for m-local storage
