Multitarget option builds gdb with support for all targets. That's
similar to gdb-multiarch package in Ubuntu or gdb with multitarget
USE-flag in Gentoo.
Nobody seems to have noticed this (except @Profpatsch) that options with
a "package" type do not get included in the manual.
So debugging this was a bit more involving because while generating the
manual there is an optionList' attribute built from the collected
attributes of all the option declarations.
Up to that point everything is fine except if it comes to
builtins.toXML, where attributes with { type = "derivation" } won't get
included, for example see here:
nix-repl> builtins.toXML { type = "derivation"; foo = "bar"; }
"<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <derivation>
<repeated />\n </derivation>\n</expr>\n"
nix-repl> builtins.toXML { type = "somethingelse"; foo = "bar"; }
"<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <attrs>
<attr name=\"foo\">\n <string value=\"bar\" />\n </attr>
<attr name=\"type\">\n <string value=\"somethingelse\" />
</attr>\n </attrs>\n</expr>\n"
The following function in libexpr/eval.cc (Nix) is responsible for toXML
dropping the attributes:
bool EvalState::isDerivation(Value & v)
{
if (v.type != tAttrs) return false;
Bindings::iterator i = v.attrs->find(sType);
if (i == v.attrs->end()) return false;
forceValue(*i->value);
if (i->value->type != tString) return false;
return strcmp(i->value->string.s, "derivation") == 0;
}
So I've renamed this now to "package" which is not only more consistent
with the option type but also shouldn't cause similar issues anymore.
Tested this on base of b60ceea, because building the dependencies on
recent libc/staging changes on master took too long.

We don't want to build all those things along with the manual, so that's
what the defaultText attribute is for.
Unfortunately a few of them were missing, so let's add them.
