The latest LTS of Node supports wasm, and this allows us to test
against it, as well as the shells.

[WebAssembly] Cleanup syscall handling in wasm.js ( #25 )
...
Also, ignore a couple of syscall by return 0 rather
than -1. This allows the musl startup code to get
furthur.

[WebAssembly] Use hardcoded list expected undefined symbols ( #21 )
...
Rather than generate wasm.syms from wasm.js (which includes
a huge superset of the number of symbols actaully expected
to be undefined at link time) simply hardcode that list as
a test file, which lld can read.

[WebAssembly] Fix shared library loading ( #17 )
...
Loading of shared libraries was broken back in:
39fde60
This change restores the ability for shared libraries to
be loaded such that they can share memory and provide
function exports to the main executable.
However the executable that libraries still need to built
in a specific way (i.e. all importing the same sized memory)
and their static globals need to be in the different address
range. This has the complication that the executables won't
run the wasm spec interpreter (since it doesn't pass in a
memory to the executables it runs). So although I'm fixing this
here in the musl repo I'm also proposiing that we remove the
continuous testing of this configurations on the wasm waterfall
in favor of concentrating on the statically linking lld case:

Add --dump-ffi-symbols argument to wasm.js ( #5 )

This allows a list of all symbols exports by wasm.js to be
generated which is usefull for passing to my prototype of
lld which takes an --allow-undefined-symbols=<filename>
argument.

Fix bugs in strcmp/strncmp/strchr
