icedtea7-native compile failure undefined reference to `main'

On hosts without /usr/include/X11/extensions, icedtea7-native compile
results in a build failure while trying to create an object file:

+/data/home/.../git/csu/../sysdeps/x86_64/start.S:118: undefined reference to `main'
[2015-03-31 15:22:53.115930161+00:00] | collect2: error: ld returned 1 exit status

The compile line shows: (-c gets eaten)
  ... -I -c -o

The makefile tries to do the following which results in a faulty build
line if /usr/include/X11/extensions doesn't exist:

  CPPFLAGS += -I$(firstword $(wildcard $(OPENWIN_HOME)/include/X11/extensions) \
                     $(wildcard /usr/include/X11/extensions))

This looks like a missed line from the following patch which removes
the need for X11/extensions:

  icedtea-ecj-disable-compilation.patch
