    tools/configure: drop BASH configure variable
    
    This is a weird variable to have in the first place.  The only user of it is
    XSM's CONFIG_SHELL, which opencodes a fallback to sh.  The scripts are 
shebang
    sh, which is already necessary to support non-Linux build environments.
    
    Make the mkflask.sh and mkaccess_vector.sh scripts executable, drop the
    CONFIG_SHELL, and drop the $BASH variable to prevent further use.
