confgure ignores compiler presets

[Anonymous]

maybe i am doing something by going the wrong way,
but i better ask here since it might be a real bug.

i am calling configure like this:

  CXX=mipsel-linux-g++ ./configure --host=mipsel-linux-g++

as a result i am getting those lines in Makedefs:

  AR              =       /usr/bin/ar
  AWK             =       gawk
  CC              =        mipsel-linux-gcc
  CXX             =        mipsel-linux-gcc
  DSO             =       $(CC)
  HTMLDOC         =
  INSTALL         =       /usr/bin/install -c
  LIBTOOL         =

watch for the CXX which is not what i have set.
i wonder if there is a pure commandline approach
for getting the CXX line right. any hints?
as i wrote - it might be a configure bug,
but i am unsure since it can be my fault either.
