DOC : build isnt a valid argument to doc/make.py

[rahulporuri]

Code Sample, a copy-pastable example if possible

python make.py build

Problem description

the docs - http://pandas.pydata.org/pandas-docs/stable/contributing.html#building-the-documentation mention that in order to do a full clean build, we will have to do

python make.py clean
python.make.py build

but the build option doesn't seem to be supported, because running the command
raises the error

Do not know how to handle build; valid args are ['all', 'latex', 'zip_html', 'latex_forced', 'upload_stable', 'build_pandas', 'upload_dev', 'upload_stable_pdf', 'upload_dev_pdf', 'auto_debug', 'html', 'clean', 'auto_dev']

Expected Output

Output of pd.show_versions()
