jemalloc documentation build glitch in version 913e9a8

[Matthew Hall]

Hello,

I'm getting some odd behavior when compiling the latest jemalloc on Ubuntu 
14.04.1 LTs.

commit 913e9a8a853a693c5b5d6c13ab86f1b46a3404f7
Date:   Fri Sep 19 22:01:23 2014 +0100

Using the following build commands:

autoconf
./configure \
--enable-autogen \
--prefix=/usr/local/jemalloc \
--with-jemalloc-prefix=je_ \
--enable-stats \
--enable-prof \
--enable-prof-libunwind \
--with-static-libunwind=/usr/lib/x86_64-linux-gnu/libunwind-x86_64.a \
--enable-fill \
--enable-valgrind \
--enable-dss \
--enable-xmalloc \
--disable-lazy-lock

make
sudo make install

The "make install" fails due to missing files unless I manually invoke 
the following doc make targets:

make build_doc_html
make build_doc_man

It appears something's going wrong in one of these places:

1) developer raw source build directions should include this
2) default make target is missing subtargets
3) should have used another target which wasn't present in the docs
4) there's some other doc I should have read besides INSTALL.

Can someone help me confirm what's going on?

Thanks,
Matthew.
