Touch all C files after checkout.stable
In order to avoid unpredictable behaviour during builds, we want
to avoid rebuilding auto-generated files. To do this, we touch all
C files for projects which do not maintain their own scripts for
doing so.
This is intended to fix random build failures in binutils
affecting ldlex-wrapper.o.
