The change in license exists in the downloaded version of PHPExcel 
1.7.6; this was not done by the phpMyAdmin team.

The idea is that we want to remove the problematic files.

For exporting in Excel 2007, my quick test worked (after removing
PHPExcel/Shared/OLE directory, OLE.php and OLERead.php).

For exporting in Excel 97-2003, it does not work, we would have to
remove the calling of class PHPExcel_Shared_OLE_PPS_FILE from
Writer/Excel5.php and maybe some other tweaking.

I suggest dropping support for "Excel 97-2003". An alternative for these 
versions is our "CSV for MS Excel" export.
