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.

-Usage: fix_libtool_files.sh <old-gcc-version> [--oldarch <old-CHOST>]
-
-    Where <old-gcc-version> is the version number of the

-    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

-
-    Note that if only the CHOST and not the version changed, you can run
-    it with the current version and the '--oldarch <old-CHOST>' arguments,
