cmake: enable binutils ld workaround for all toolchains at build-time (revert)

The change was valid, but caused an annoying warning with perfectly
working non-binutils ld linkers:
```
ld: warning: ignoring duplicate libraries: 'my/path/usr/local/lib/libcrypto.a'
```
(seen with Apple clang, when using static `libcrypto.a`)

It means that for the binutil ld hack to work at consumption-time, curl
must be built with the same picky binutils (gcc) toolchain.

Reverts 795433b923fc7953ae0a20b44249055fe334ae33 #20434

Closes #20594
