Subject: [PATCH] Remove duplicate build configuration for ARM64/AAPCS/ELF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove duplicate entry from `Jamfile.v2` that prevented the selection of `fcontext` implementation with the following configuration:
```
<abi>aapcs <address-model>64 <architecture>arm <binary-format>mach-o <threading>multi <toolset>gcc
```
The error was as follows:
```

```

The duplicate code was introduced in d81d611fa22e83e7a71ced2e3e354a3d776a9bd4 and 35ddf2103e1e38573e6f80e711154e7956abd425.
