When setting up tm.h, convert "vax/vax.h" into "config-vax.h" rather
than "[.config.vax]vax.h" for #include so it will work from [.cp]
subdirectory; copy vax.h to config-vax.h as part of configuration
setup.  Also, manually include cc1plus in the list of buildable
compilers (a temporary measure; it should process cp/Makefile.in like
it does for primary makefile).

Use `=' rather than `:=' when setting up CC, so that `gcc' can be
defined as a foreign command if necessary; eliminate `set
symbol/scope=noGlobal' for same reason; use `=' with all other
symbols, for consistency; add explicit .obj extension to some lists of
object files passed to the linker; general cleanup of the command text
echoed during execution.
