Log:
  PORTS_MODULES: Don't leak in CC/CXX/CPP.
  
  These may have ccache in them or -target/--sysroot from external
  compiler or SYSTEM_COMPILER support.  Many ports do not support
  a CC with spaces in it, such as emulators/virtualbox-ose-kmod.
  Passing --sysroot to ports makes no sense as ports doesn't support
  --sysroot currently.
  If these variables need to be overridden for ports then they can
  be set in make.conf or passed as make arguments.
