Subject: [PATCH 6/6] Make the collector build with threads
In an extremely limited way for now:
- No extra threads
More threads always lead to exactly one borked thread that's stuck
in no man's land, doing who-knows-what, and definitely not
responding to signals.
However, the APIs are there and they work, so they *can* be used to
make threads.
- No fork handling
Seems borked for unknown reasons.

# Patches for bdwgc on SerenityOS
## `0001-Teach-os_dep-and-gcconfig.h-about-serenity.patch`
Teach os_dep and gcconfig.h about serenity
## `0002-Error-on-unknown-arch.patch`
Error on unknown arch
## `0003-Teach-dyn_load.c-about-serenity.patch`
Teach dyn_load.c about serenity
## `0004-Teach-bdwgc-about-serenity-signals.patch`
Teach bdwgc about serenity signals
Serenity doesn't have the realtime POSIX signals, so use SIGXCPU and
SIGXFSZ instead.
## `0005-Explicitly-link-with-pthread.patch`
Explicitly link with pthread
The cmakelists was using the wrong variable to link against pthread.
## `0006-Make-the-collector-build-with-threads.patch`
Make the collector build with threads
In an extremely limited way for now:
- No extra threads
More threads always lead to exactly one borked thread that's stuck
in no man's land, doing who-knows-what, and definitely not
responding to signals.
However, the APIs are there and they work, so they *can* be used to
make threads.
- No fork handling
Seems borked for unknown reasons.
