On Mac OS X 10.8 sed, the | operator isn't available in basic REs,
only in extended ones. The null string also has to be expressed with
().
Another Mac OS X-compatible version of the RE is
's/\.c\(xx\)\{0,1\}//'.
Both of these versions have been tested for compatibility with GNU sed.
A third alternative is to omit generating these dummy deps altogether,
and prefixing the include statements in the Makefiles with a '-',
which haves make ignore any failures in including those files.
