Simplify populate: no need to be too smart.
If someone is playing us tricks, let him/her be beaten back.
Chances are he/she knows what happens when he/she finds out it does not work any more!

152 \`configure' configures crosstool-NG ${VERSION} to adapt to many kind of systems.
154 USAGE: ./configure [OPTION]...
156 Defaults for the options are specified in brackets.
159 -h, --help display this help and exit
160 --force force ./configure to complete, even if one or more
161 tools were not found. Use at your own risk, only if
162 you know what you are doing!
164 Installation directories:
165 --prefix=PREFIX install files in PREFIX [${PREFIX_DEFAULT}]
166 --local don't install, and use current directory
168 By default, \`make install' will install all the files in
169 \`${PREFIX_DEFAULT}/bin', \`${PREFIX_DEFAULT}/lib' etc. You can specify
170 an installation prefix other than \`${PREFIX_DEFAULT}' using \`--prefix',
171 for instance \`--prefix=\${HOME}'.
173 For better control, use the options below.
175 Fine tuning of the installation directories:
176 --bindir=DIR user executables [PREFIX/bin]
177 --libdir=DIR object code libraries [PREFIX/lib]
178 --docdir=DIR info documentation [PREFIX/share/doc]
179 --mandir=DIR man documentation [PREFIX/share/man]
182 --with-contrib=XXX Include externally contributed features found in the
183 contrib/ sub-directory. Set to a comma-separated list
184 of features. Use 'all' to use all contributions, and
185 'list' to see which are available.
