b908733257 Install Firefox

Attempting to cross-compile Firefox will be rather challenging.  It has
loads of dependencies, written in a variety of languages.  Some issues
are more interesting than others.  Notably, _dev-libs/nss_ needs to be
installed on the host in order to cross-compile itself, but its ebuild
does not specify this ([Bug 759127][0]).  Also the build system for
_gnome-base/librsvg_ is broken: [Gentoo Bug 835758][1], [GNOME
Issue #810][2].  Cross-compiling _dev-libs/gobject-introspection_ is
also broken ([Bug 759127][3], [850895][4]).

With all of these changes, we can get to the point where Portage starts
building Firefox, it will take hours and all of my machine's resources,
so I haven't tested if will actually build.  We shall see once Jenkins
tries it...

faccf8200f Build Firefox w/ gcc

Building _www-client/firefox_ fails fairly early with an error about not
being able to find `aarch64-unknown-linux-gnu-clang-19` to use as `CC`.
I have not been able to determine what is supposed to provide this
program/symlink, nor much information at all about cross-compiling with
Clang, really.  We shall try building Firefox with GCC, since we know
that toolchain is complete.

c93bceeb56 Install Firefox from Gentoo binpkg

Unfortunately, even building Firefox with GCC fails:

> 3:30.02 [gecko-profiler 0.1.0] /../lib/gcc/aarch64-unknown-linux-gnu/14/include/g++-v14/cstdlib:79:15: fatal error: 'stdlib.h' file not found
> 3:30.02 [gecko-profiler 0.1.0] thread 'main' panicked at tools/profiler/rust-api/build.rs:104:10:
> 3:30.02 [gecko-profiler 0.1.0] Unable to generate bindings: ClangDiagnostic("/../lib/gcc/aarch64-unknown-linux-gnu/14/include/g++-v14/cstdlib:79:15: fatal error: 'stdlib.h' file not found\n")

Clearly, something is misconfigured, because `stdlib.h` does indeed
exist.  I am not sure what, though, and I am getting tired of messing
with this.

Fortunately, the official Gentoo binary package project has a build of
_www-client/firefox_ for ARM64.  It has a rather different USE flag
configuration than what we did, though, so we have to pull in quite a
few more dependencies.

We can't just add _www-client/firefox_ to `install.packages` because
Aimee OS runs `emerge` with `--getbinpkgonly`, which implies
`--binpkg-changed-deps=y`.  This since we want to build everything
_except_ Firefox locally, the dependency graph is quite a bit different,
so Portage ignores the binary package and will try to build
_www-client/firefox_ from source.

To work around this limitation, we need to install Firefox manually in
the `customize.sh` script in two phases.  First, we install all of its
dependencies in the build root (`/usr/aarch64-…`), but not Firefox
itself, to get binpkgs for them.  Then, we install _www-client/firefox_
in the target root (`/mnt/gentoo`) with the `--getbinpkg` and
`--usepkgonly` flags.

Hopefully, one day I can figure out how to cross-compile Firefox (and it
doesn't take days to build once I do), and we can remove this hackery.
