Adding `ruby` to `PREP` causes the following circular dependencies
because `PREP` is used as a prerequisite by some targets required to
build `ruby` target itself.
```
make: Circular .rbconfig.time <- ruby dependency dropped.
make: Circular builtin_binary.inc <- ruby dependency dropped.
make: Circular ext/extinit.c <- ruby dependency dropped.
make: Circular ruby <- ruby dependency dropped.
```
Adding a new Make variable like `EXTPREP` only for exts may be also
reasonable, but it would introduce another complexity into our build
system. `-bundle_loader` doesn't care that link-time and run-time
loader executables are different as long as bound symbols are provided,
so it's ok to resolve from miniruby to simplify our build.
ld64 shipped with Xcode 14 emits a warning when using `-undefined
dynamic_lookup`.
```
ld: warning: -undefined dynamic_lookup may not work with chained fixups
```
Actually, `-undefined dynamic_lookup` doesn't work when:
1. Link a *shared library* with the option
2. Link it with a program that uses the chained-fixup introduced from
macOS 12 and iOS 15
because `-undefined dynamic_lookup` uses lazy-bindings and they won't be
bound while dyld fixes-up by traversing chained-fixup info.
However, we build exts as *bundles* and they are loaded only through
`dlopen`, so it's safe to use `-undefined dynamic_lookup` in theory.
So the warning produced by ld64 is false-positive, and it results
failure of option checking in configuration. Therefore, it would be an
option to ignore the warning during our configuration.
On the other hand, `-undefined dynamic_lookup` is already deprecated on
all darwin platforms except for macOS, so it's good time to get rid of
the option. ld64 also provides `-bundle_loader <executable>` option,
which allows to resolve symbols defined in the executable symtab while
linking. It behaves almost the same with `-undefined dynamic_lookup`,
but it makes the following changes:
1. Require that unresolved symbols among input objects must be defined
in the executable.
2. Lazy symbol binding will lookup only the symtab of the bundle loader
executable. (`-undefined dynamic_lookup` lookups all symtab as flat
namespace)
This patch adds `-bundle_loader $(RUBY)` when non-EXTSTATIC
configuration by assuming ruby executable can be linked before building
exts.
