[tex-live] make clean

[Thomas Esser]

> Two ways:

I am for the third way. I build outside the source dir and just do

  p4 sync somedate # texlive -> /t/texlive
  mkdir /build/XY
  cd /build/XY
  /t/texlive/Build/source.development/TeX/configure
  make
  make install
  rm -rf /build/XY # optional
  p4 sync someotherdate
  mkdir /build/XYZ
  cd /build/XYZ
  /t/texlive/Build/source.development/TeX/configure
  make
  make install

That "build outside the source dir" might only work with GNU make.
And the "extra" stuff will not yet work completely, too (that's why my
example only configures the TeX directory, not the "real" top-level of
TeX Live).

Anyway, I agree that "make clean" should remove .c files that are
generated during a regular "make".
