The perl binaries included in the toolchains are not static binaries

The perl binaries included in the toolchains are not static binaries. Instead, they link against a number of libraries:

```shell-session
ldd perl
linux-vdso.so.1 (0x00007ffc8a09a000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f525fd82000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f525fd7d000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f525fc96000)
libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007f525fc5c000)
libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f525fc57000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f525fa2f000)
/lib64/ld-linux-x86-64.so.2 (0x00007f525fda0000)
```

This makes the rules non-hermetic and prevents usage in clean environments like nixOS.
The issue also has been raised with the source of the perl binaries some time ago: https://github.com/skaji/relocatable-perl/issues/13

Some background:

I want to compile openssl hermetically within bazel.

Start by reproducing the issue with `ldd perl` on the Perl binaries included in the toolchains, then review the linked relocatable-perl issue for the source-side context. Done means the included Perl binaries no longer depend on host libraries and can run in clean environments such as NixOS.
