Update to 0.32.2

  Do not pass *all* CFLAGS flags to CXXFLAGS.  This fixes builds
  where, for example, clang is used as a C compile and gcc is used as
  a C++ compiler. Also, MKC_CHECK_* variables update MKC_CPPFLAGS
  instead of MKC_CFLAGS.

  Avoid "install -d /" if there is nothing to install.  This fixes
  some failures on some systems/conditions and improves support for
  foreign install(1) programs, e.g., (UCB install on Solaris)

  Fixes for CFLAGS containing -O2 and -D_FORTIFY_SOURCE=n

  main.mk: clean-ups for target "cleandir" and "clean"
