These are not perfect, but they are useful.  If you use csh/tcsh, 

   alias __makevars      'make -ndv |& perl -ne '\''print "$1\n" if /^(?:Command|Global|Internal):(\S+?)\s+/;'\'' | sort -u'

   complete make         'C/F/(FORMATS= FORMATS=html FORMATS=html-split FORMATS=pdf)/' \
                         'p/1/`make -V .ALLTARGETS`/' \

'make' [space] [tab] completes from available targets.
'make -V' [space] [tab] completes from known variables.
Both probably miss some.  The variable completion could be 
faster.  Improvements welcome.

(The first is for me, to complete 'make FORMATS=' for docs.)
