scripts: simplify and fix the toolchain config script

   296 \`configure' configures crosstool-NG-${VERSION} to adapt to many kind of systems.
   297 
   298 USAGE: ./configure [OPTION]...
   299 
   300 Defaults for the options are specified in brackets.
   301 
   302 Configuration:
   303   -h, --help              display this help and exit
   304       --force             force configure to continue, even in case
   305                           some pre-requisites are missing
   306 
   307 Installation directories:
   308   --prefix=PREFIX         install files in PREFIX [${PREFIX_DEFAULT}]
   309   --local                 don't install, and use current directory
   310 
   311 By default, \`make install' will install all the files in
   312 \`${PREFIX_DEFAULT}/bin', \`${PREFIX_DEFAULT}/lib' etc.  You can specify
   313 an installation prefix other than \`${PREFIX_DEFAULT}' using \`--prefix',
   314 for instance \`--prefix=\${HOME}'.
   315 
   316 For better control, use the options below.
   317 
   318 Fine tuning of the installation directories:
   319   --bindir=DIR            user executables [PREFIX/bin]
   320   --libdir=DIR            object code libraries [PREFIX/lib]
   321   --docdir=DIR            info documentation [PREFIX/share/doc]
   322   --mandir=DIR            man documentation [PREFIX/share/man]
   323 
   324 Optional Features:
   325   --with-install=PATH     Specify the full PATH to GNU install
   326   --with-make=PATH        Specify the full PATH to GNU make >= 3.80
   327   --with-grep=PATH        Specify the full PATH to GNU grep
   328   --with-sed=PATH         Specify the full PATH to GNU sed
   329   --with-bash=PATH        Specify the full PATH to bash >= 3.0
