[BUG] TenDRA binary support missing

**Describe the bug**
TenDRA can generate assembly, but we're missing some exact paths on our instances.
They are I think installed by `libc6-dev:i386`
```
dpkg -S /usr/lib/i386-linux-gnu/crt1.o
libc6-dev:i386: /usr/lib/i386-linux-gnu/crt1.o
```
and we only have `libc6-dev-i386` installed (https://github.com/compiler-explorer/infra/blob/master/setup.sh#L41).

**Error message**
```

x86 tendra (trunk) - cached
/usr/bin/ld: cannot find /usr/lib/i386-linux-gnu/crt1.o: No such file or directory

/usr/bin/ld: cannot find /usr/lib/i386-linux-gnu/crti.o: No such file or directory

Compiler returned: 1
```

**Additional context**
Binary support is currently disabled for TenDRA to not show these errors.

Inspect the linked infra repository's setup.sh around line 41 and compare the installed i386 development package with the paths required by TenDRA. Verify that the crt1.o and crti.o paths become available, then check the compiler configuration that currently disables TenDRA binary support and confirm compilation succeeds without the linker errors.
