[Buildroot] [PATCH 03/11] manual: update prerequisite.txt

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello Samuel,

Good work. I'll try to reply to your introduction e-mail soon with
general comments. Below some specific comments on this patch.

autoconf/automake/libtool are not needed.

gawk is not in the list of mandatory dependencies. For example, the
crosstool-ng package builds host-gawk because it needs gawk. So this
tool is not current part of the mandatory dependencies.

None of the version control systems are part of the mandatory
dependencies. They will only be needed if the user has selected only
one package that needs to be fetched from one of those version control
system.

I know it's nitpicking, but I think that one of the good thing with
Buildroot is that the amount of mandatory dependencies on the host is
relatively small, so it would be a shame to mark all those tools are
mandatory even though they are not.

Except ncurses5, none of these libraries should be needed, I think. We
build host-zlib when needed, and I don't see where the other libraries
are coming from.

This one should be part of the optional dependencies, people /using/
Buildroot will not need to re-generate the documentation.

This one is already listed above as a mandatory dependency.

Huh, why?!? We build host-libglib2 when needed, and the other ones
should be fixed if they don't build correctly without those host
components installed.

We don't have Java packages anymore in Buildroot, at least at the
moment.

Best regards,
