[cfe-dev] make check-all when configure with --with-gcc-toolchain gives false result?

[Larry Evans]

When configuring with:
--{---cut here---
  #!/bin/bash
  this_dir=`pwd`
  ls $this_dir/../../../llvm.src/configure
  $this_dir/../../../llvm.src/configure \
    --prefix=$this_dir/../install \
    --enable-optimized=YES \
    --with-gcc-toolchain=/home/evansl/download/gcc/4.8-20121028/install \
    #
--}---cut here---

followed by `make`; then `make check-all`, results in errors which
include:

The above error messages suggest to me that maybe the test does not
take into account the:

    --with-gcc-toolchain=/home/evansl/download/gcc/4.8-20121028/install \

argument to configure.  Is that right?  If so, is there some way to
modify the test to take this into account?

TIA.
