I'm attaching a patch against 3.1.5 that should work correctly, I think.
If the stamp-eg file is not present, then the 'eg' tree will be built
inside the build directory tree.

Furthermore, it is not necessary to include the eg tree in the distro,
since it is generated by the build process, so both eg and stamp-eg
can be removed from EXTRA_DIST.

Also, some xgawk users found that the extract script may fail in some
locales, so this patch specifies the 'C' locale.

In addition to the patch against 3.1.5, I am attaching a copy of the
resulting Makefile.am file.
