this makes it much easier to understand test failures.
before:
```
diff of stderr:
1 error: linking with `LINKER` failed: exit status: 1
2 |
- ld: Undefined symbols:
4 _CFRunLoopGetTypeID, referenced from:
5 clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
after:
```
=== HAYSTACK ===
error: linking with `cc` failed: exit status: 1
|
= note: use `--verbose` to show all linker arguments
= note: Undefined symbols for architecture arm64:
"_CFRunLoopGetTypeID", referenced from:
main::main::hbb553f5dda62d3ea in main.main.d17f5fbe6225cf88-cgu.0.rcgu.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: aborting due to 1 previous error
=== NEEDLE ===
_CFRunLoopGetTypeID\.?, referenced from:
thread 'main' panicked at /Users/jyn/git/rust-lang/rust/tests/run-make/linkage-attr-framework/rmake.rs:22:10:
needle was not found in haystack
```
this also fixes a failure related to missing whitespace; we don't actually care about whitespace in this test.
