Why does the option have a -unknown-unknown suffix?
Compilers often consider their target as a triplet in the form machine-vendor-os, such as x86-pc-linux, which would describe a compiler targeting x86 IBM compatible machines running Linux. In the case of webasm, the machine target is webasm, but the vendor/OS are irrelevant and not known at compile time.
Thanks for the clear explanation :)
