Bryan Drewery 3bed45ab81 META MODE: Rework [bootstrapped] tools PATH support.
- Support more of the toolchain from TOOLSDIR.
- This also improves 'make bootstrap-tools' to pass, for example,
  AS=/usr/bin/as to Makefile.inc1, which will tell cross-tools to use
  external toolchain support and avoid building things we won't be using
  in the build.
- Always set the PATH to contain the staged TOOLSDIR directories when
  not building the bootstrap targets.

  The previous version was only setting this at MAKE.LEVEL==0 and if the
  TOOLSDIR existed.  Both of these prevented using staged tools that were
  built during the build though as DIRDEPS with .host dependencies, such
  as the fix for needing usr.bin/localedef.host in r291311.
  This is not a common tool so we must build and use it during the build,
  and need to be prepared to change PATH as soon as it appears.

  This should also fix the issue of host dependencies disappearing from
  Makefile.depend and then reappearing due to the start of the fresh build not
  having the directory yet, resulting in the tools that were built not actually
  being used.
- Only use LEGACY_TOOLS while building in Makefile.inc1.  After r291317
  and r291546 there is no need to add LEGACY_TOOLS into the PATH for
  the pseudo/targets/toolchain build.
- Because the pseudo/targets/toolchain will now build its own
  [clang-]tblgen, the special logic in clang.build.mk is no longer needed.
- LEGACY_TOOLS is no longer used outside of targets/pseudo/bootstrap-tools
  so is no longer passed into the environment in its build.
