Look more closely ;) Shell expands the variables into the herefile. So
if make is picked from a nonstandard location, the debian/rules
shebang becomes #!/home/masahiro/bin/make -f

As I said the price of this hack is that if use make from non-standard
location, the source package won't build anywhere else. Then again,
you probably shouldn't use non-standard tools when building source
packages for others to consume.
