Ok I now think the whole native-ecj thing is a misnomer and not related.
The lack of a binary would mean that the interpreted version would be used
anyway by the javac.in script, but a --with-icedtea build doesn't use
this anyway.
/home/matthew/Code/Java/IcedTea/icedtea7/bootstrap/jdk1.6.0/bin/javac
will actually
be a symlink to /usr/lib/jvm/java-7-icedtea/bin/javac so the two
branches of the if
statement above are equivalent.

So the problem is:

/home/matthew/Code/Java/IcedTea/icedtea7/bootstrap/jdk1.6.0/bin/javac
-J-Xmx512m -g -d extra-lib \
            -source 1.5 \
            -sourcepath extra -cp
/home/matthew/Code/Java/IcedTea/icedtea7/bootstrap/jdk1.6.0/jre/lib/rt.jar
\
            -bootclasspath '' @extra-source-files.txt ; \

And I have a feeling it may be that your IcedTea is too old to use for
a --with-icedtea build
(i.e. it lacks some features of the netx support that the build
expects to find there).  A full
build would compile them instead of expecting them to be in rt.jar.
I'll try and do a --with-icedtea
build myself with current IcedTea7 and see if I get the same failure,
but this is probably because
the one in Ubuntu Gutsy Gibbon will be very old now.
