No libtool archives installed?

I currently have
```
libunwind 1.3.1 hf484d3e_1000 conda-forge
```
and
```
gperftools 2.7 h767d802_2 conda-forge
```
`libtcmalloc.la` which is installed by `gperftools` has `libunwind.la` as a dependency:
```
# Libraries that this one depends upon.
dependency_libs=' -L/home/lindad/miniconda3/envs/moose-petsc/lib /home/lindad/miniconda3/envs/moose-petsc/lib/libunwind.la -lpthread'
```
But `conda install libunwind` doesn't appear to give me any libtool archives:
```
(moose-petsc) lindad@pop-os:~/miniconda3/envs/moose-petsc$ find . -iname "*libunwind*"

```
Is this the desired behavior?
