The reason is:

# New autoconf (>= 2.60?) make a configure with --docdir=DIR etc flags.
# However, in order to support older autoconf's we don't use them.

Hmm, code to set datarootdir should come from autoreconf, when it makes
configure. Can you please tell me what these commands say for you in a
configured GHC tree?

autoreconf --version
make show VALUE=bindir
make show VALUE=datarootdir
make show VALUE=datadir
make show VALUE=docdir
