   8 Usage: fix_libtool_files.sh <old-gcc-version> [--oldarch <old-CHOST>]
   9
  10     Where <old-gcc-version> is the version number of the
  11     previous gcc version.  For example, if you updated to
  12     gcc-3.2.1, and you had gcc-3.2 installed, run:
  13
  14       # fix_libtool_files.sh 3.2
  15
  16     If you updated to gcc-3.2.3, and the old CHOST was i586-pc-linux-gnu
  17     but you now have CHOST as i686-pc-linux-gnu, run:
  18
  19       # fix_libtool_files.sh 3.2 --oldarch i586-pc-linux-gnu
  20
  21     Note that if only the CHOST and not the version changed, you can run
  22     it with the current version and the '--oldarch <old-CHOST>' arguments,
  23     and it will do the expected:
  24
  25       # fix_libtool_files.sh `gcc -dumpversion` --oldarch i586-pc-linux-gnu
