- Extra memory because ASAN needs it
- The environment variables to make the sanitizers more useful
- LD_PRELOAD because the ASAN DSO needs to be the first in the list
- The sanitizer library packages
- Disable syscall filters because they interfere with ASAN
- Disable systemd-hwdb-update because it's super slow when systemd-hwdb
is built with sanitizers
- Take the value for meson's b_sanitize option from the SANITIZERS
environment variable

issue a directory command to make sure gdb can find systemd's
source files. Let's put this in a .gdbinit file so it's executed
automatically when we run gdb.
