My thinking behind this was that if the no-eh libs are in the default location
then there's a risk they're used if things are misconfigured and the `eh` path
is lost. By separating these directories entirely it'd help catch
misconfigurations because the libraries would be entirely missing as opposed to
possibly overlapping.
For now with wasi-sdk only libcxx and friends are compiled twice, I was
thinking that there'd be libc in the "default location" and then libcxx would
be located both in the "eh" and "noeh" locations compiled separately
