New <c:configure> command fails

[Chandler Carruth <chandlerc@…>]

The configure command correctly runs "./configure", but the script dies very early on:

[INFO    ] Executing build step "configure"
[INFO    ] checking build system type... i686-pc-linux-gnu
[INFO    ] checking host system type... i686-pc-linux-gnu
[INFO    ] checking target system type... i686-pc-linux-gnu
[INFO    ] checking for a BSD-compatible install... /usr/bin/install -c
[INFO    ] checking whether build environment is sane... yes
[INFO    ] checking for gawk... gawk
[ERROR   ] configure: error: C compiler cannot create executables

[ERROR   ] See `config.log' for more details.
[INFO    ] checking for gcc... gcc
[ERROR   ] Build step configure failed
[WARNING ] Build step configure failed

things that would be useful in finding out why this happens:

• When the build process errors out, or when "--debug" is set on the slave, leave the directory w/ the source so that the config.log can be examined.
• In --debug level of output, show the exact command being run for <c:configure>

With either/both of these, I can probably find the problem.

The actual command executed should be displayed in --debug mode, actually.

The problem here was that the CFLAGS and CXXFLAGS were quoted. That is appropriate when invoking ./configure through the shell, but fails when invoking it programmatically.

In addition, the current working directory wasn't be set, so ./configure created its output files in the directory that bitten-slave was being run from.

Both of these problems should be fixed in [251].
