+ First we find all the files under the gcc/config directory that are named
+ either <filename>linux.h</filename> or <filename>linux64.h</filename>.
+ For each file found, we copy it to a file of the same name but with an
added
+ suffix of <quote>.orig</quote>. Then the first sed expression prepends
+ <quote>/tools</quote> to every instance of <quote>/lib/ld</quote>,
+ <quote>/lib64/ld</quote> or <quote>/lib32/ld</quote>, while the second one
+ replaces hard-coded instances of <quote>/usr</quote>. Then we add our
define
+ statements which alter the include search path to the end of the file.
Finally,
+ we use <command>touch</command> to update the timestamp on the copied
files.
+ When used in conjunction with <command>cp -u</command>, this prevents
unexpected
+ changes to the original files in case the command is inadvertently run
twice.
