toolchain.eclass: drop fix_libtool_files.sh

fixlafiles.awk can mangle two things in .la fils:

1. patch reference 'from .../libstdc++.la' to '-lstdc++'
2. change ${CHOST} when user switches CHOST and rebuilds the system

[1.] is not relevant since gcc-4 in Gentoo where we started deleting
libstdc++.la on gcc installation. Nothing should embed libstdc++.la
paths anymore.

[2.] is a rare one-off step that has a lot more caveats than just .la
file patching.

Generally .la files are tracked by package manager and should not be
changed after they are installed on disk. 'fix_libtool_files.sh' breaks
that invariant.

On top of that portage's FEATURES=fixlafiles removes nested .la files
references.

Let's remove 'fix_libtool_files.sh' and 'fixlafiles.awk' completely.
If really needed we can reintroduce it as a separate tool.
