|/ / | | | | | | | | | | | | `if(NOT DEFINED)` is not appropriate since a variable that contains `-NOTFOUND` still counts as `DEFINED`. This can cause issues if configuration fails, writes `-NOTFOUND` to the cache, and is then restarted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This involves very few changes, all typical to WASM ports: * WASM doesn't currently support threads or atomics so those are disabled. * WASM doesn't currently support exceptions so the exception machinery is stubbed out. * WASM doesn't (and can't) have mmap(), so an emulation library is used. That library currently doesn't support MAP_SHARED flags, so MAP_PRIVATE is used instead. There is also an update to bring ECP5 bbasm CMake rules to parity with iCE40 ones, since although it is possible to embed chipdb into nextpnr on WASM, a 200 MB WASM file has very few practical uses. The README is not updated and there is no included toolchain file because at the moment it's not possible to build nextpnr with upstream boost and wasi-libc. Boost requires a patch (merged, will be available in boost 1.74.0), wasi-libc requires a few unmerged patches.
