[tex-live] devnag configure problem

[Roozbeh Pournader]

Running source.development's configure from another build directory gives 
an error about 'devnag':

------
$ cd /opt/texlive/build
$ rm -rf *
$ /home/roozbeh/texlive/Build/source.development/configure \
                    --prefix=/opt/texlive --datadir=/opt/texlive
[...]
configure: error: source directory already configured; run make distclean there first
configure: error: /home/roozbeh/texlive/Build/source.development/TeX/texk/devnag/configure failed for devnag
configure: error: /home/roozbeh/texlive/Build/source.development/TeX/texk/configure failed for texk
configure: error: /home/roozbeh/texlive/Build/source.development/TeX/configure failed for TeX
------

This will be solved by removing the following files from the
Perforce tree:

//depot/Build/source.development/TeX/texk/devnag/config.cache
//depot/Build/source.development/TeX/texk/devnag/config.h
//depot/Build/source.development/TeX/texk/devnag/config.log
//depot/Build/source.development/TeX/texk/devnag/config.status
//depot/Build/source.development/TeX/texk/devnag/Makefile
//depot/Build/source.development/TeX/texk/devnag/stamp-h
