I prefer keeping all variables in GN-style and then having the users rebase as
needed. This gives a bit more flexibility since future users may want this
directory relative to different places.

So I would keep this as:
  nacl_toolchain_dir = "//native_client/toolchain"
in the toolchain file where you need the absolute path frequently, maybe make a
new "abs_nacl_toolchain" var, and in the ppapi file when you compute
glibc_toolchain_dir, just put the rebase path in there.

Done.

+os_toolchain_dir = "${nacl_toolchain_dir}/${host_os}_x86"
