Details:

While I was compiling lastest release version of Wget (1.19.1) via Git
checkout to verify a URL filtering issue, I ran into a build failure.

>From a look at output from Make, it turned out that Make somehow tried to
invoke `gperf` command, and failed as I didn't have gperf installed on my
system. Gperf <https://www.gnu.org/software/gperf/> requirement is *not
mentioned anywhere in documentation*: README
<https://git.savannah.gnu.org/cgit/wget.git/tree/README?h=v1.19.1>,
README.checkout
<https://git.savannah.gnu.org/cgit/wget.git/tree/README.checkout?h=v1.19.1>
and INSTALL
<https://git.savannah.gnu.org/cgit/gnulib.git/tree/doc/INSTALL?id=916a632413a6c0af72c7b61f36e3eb8400b858cc>
file. Also, *both `bootstrap` and `configure` didn't complain about it* being
missing either.

Exact steps to reproduce:

* Uninstall `gperf` (if installed)
* Run `git clone https://git.savannah.gnu.org/git/wget.git wget.git`
* Go into `wget.git` directory
* Run `git checkout v1.19.1`
* Run `./bootstrap`
* Run `./configure --prefix=/opt/wget-1.19.1 --enable-assert`
* Run `make V=1`

You would see that Make ends with an error like following:

gperf -m 10 ./unicase/special-casing-table.gperf >
./unicase/special-casing-table.h-t && \
        mv ./unicase/special-casing-table.h-t ./unicase/special-casing-table.h
/bin/bash: gperf: command not found
make[2]: *** [unicase/special-casing-table.h] Error 127
make[2]: Leaving directory `/home/window/prog/wget.git/lib'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/window/prog/wget.git'
make: *** [all] Error 2


Bootstrap output, configure output, config.log, and full Make output are
attached as `wget1.19.1git-gperferror.zip` for a reference.

If `gperf` was installed, the build would succeed. This problem affects only
Git version of Wget; the tarball version builds fine.

Wget: 1.19.1 (git)
Gnulib: v0.1-1130-g916a632 (git)
Autoconf: 2.69-1 (debian)
Gperf: 3.0.3-1+b1 (debian)
System: Debian GNU/Linux 7.0 Wheezy i386
