Handling problematic GCC in Gentoo ;-)

almuqaddis ~ # gcc-config 5
* Switching to i686-pc-linux-gnu-3.4.4 compiler ... [ ok ]

* If you intend to use the gcc from the new profile in an already
* running shell, please remember to do:

* # source /etc/profile

almuqaddis ~ # . /etc/profile

almuqaddis ~ # fix_libtool_files.sh
Usage: fix_libtool_files.sh [--oldarch ]

Where is the version number of the
previous gcc version. For example, if you updated to
gcc-3.2.1, and you had gcc-3.2 installed, run:

# fix_libtool_files.sh 3.2

If you updated to gcc-3.2.3, and the old CHOST was i586-pc-linux-gnu
but you now have CHOST as i686-pc-linux-gnu, run:

# fix_libtool_files.sh 3.2 --oldarch i586-pc-linux-gnu

Note that if only the CHOST and not the version changed, you can run
it with the current version and the '--oldarch ' arguments,
and it will do the expected:

# fix_libtool_files.sh `gcc -dumpversion` --oldarch i586-pc-linux-gnu

almuqaddis ~ # fix_libtool_files.sh 3.4
