7f96638723 contrib: add macOS fixup_chains check to security-check (fanquake)
3dca683cb7 build: support -no_fixup_chains in ld64 (fanquake)
Pull request description:
Followup to #27676, adding the check for chained fixups.
Somewhat annoyingly, we have to patch support for `-no_fixup_chains` into ld64. As it doesn't seem to have been added [until a later version](59a99ab603/src/ld/Options.cpp (L4172)).

Fix warnings for these files when ./test/lint/lint-python.py is run using
mypy 0.991 (released 11/2022) and later:
"By default the bodies of untyped functions are not checked, consider using
--check-untyped-defs [annotation-unchecked]"
For details, see:
https://mypy-lang.blogspot.com/2022/11/mypy-0990-released.html
This change allows to use the `test-{security,symbol}-check.py` scripts
when building out of source tree with no need to link scripts into the
build directory.
These test-*-check scripts should compile "test" binaries in a way that
is as close to what autotools would do, since the goal is to make sure
that if we run the *-check script, they can correctly detect flaws in
binaries which are compiled by our autotools-based system.
Therefore, we should emulate what happens when the binary is linked in
autotools, meaning that for C binaries, we need to supply the CFLAGS,
CPPFLAGS, and LDFLAGS flags in that order.
Note to future developers: perhaps it'd be nice to have these
test-*-check scripts be part of configure.ac to avoid having to manually
replicate autoconf-like behaviour every time we find a discrepancy. Of
course, that would also mean you'd have to write more m4...
This is important to make sure that we're not testing tools different
from the one we're building with.
Introduce determine_wellknown_cmd, which encapsulates how we
should handle well-known tools specification (IFS splitting, env
override, etc.).
Check that sections are appropriately separated in virtual memory,
based on their (expected) permissions. This checks for missing
-Wl,-z,separate-code and potentially other problems.

Some trivial maintenance to avoid having to do it again after the 0.17 branch off.
(The scripts to do this are in `./contrib/`)

Perform the following ELF security checks:
- PIE: Check for position independent executable (PIE), allowing for address space randomization
- NX: Check that no sections are writable and executable (including the stack)
- RELRO: Check for read-only relocations, binding at startup
- Canary: Check for use of stack canary
Also add a check to symbol-check.py that checks that only the subset of
allowed libraries is imported (to avoid incompatibilities).
