support cc_benchmark target type
create ~/.profile if it doesn't exist and the next line of PATH is useless.
fix typo in README
let's support zsh for real :)

`~/.profile` is not used for zsh FYI.

Instead, `~/.zprofile` is used, but this file is only for login shell. We need
to support interactive shell as well (I use PuTTY a lot...)

I understand that there's always a workaround for zsh users to source the
~/.profile, but that requires an extra step for users. Using this code would
make zsh users' life easier. :D

a few fixes about the install script
fix the following issue:

support we have the following directory structure:

root/
    a/
        a.cc
    b/
        b.h

and in a.cc, we include b.h

    #include "b.h"

and in the original implementation, it would be changed to

    #include "/b/b.h"

this is because `${hdr_path#$root}` operation is incomplete for this scenario:

        hdr_path = "/root/b/b.h"
        root = /root"
