SConstruct: added a more meaningful message for the error checking of the
python 2.7 headers
One of the most common errors during the installation of gem5 is the one
related to the failure of the check of the Python2.7 headers in the
SConstruct file. In some cases the headers are correctly installed, but a
wrong selection of the C compiler can make this check fail. This commit
wants to add some useful information this error message.
