Description

Fix issue #2297.

The old code push full path to the parent directory, if we run wasmer as below:

wasmer  run --mapdir=/:. --mapdir=./:.  ./wasm/clang.wasm -- -cc1 -triple wasm32-unknown-wasi -isysroot /sys -internal-isystem /sys/include -emit-obj -o ./source/hello/
hello.o ./source/hello/hello.c

The out_path become to : ./source/hello/source/hello/hello.o, it will trigger an I/O error.

close #2297

Good fix! I'll wait for @MarkMcCaskey review as he has more insight on the WASI internals :)

Spend some time to figure how to add unit test for WASI fs.
Seems we don't have make wasitests now?

Thanks for the fix! Just a small tweak on the fix itself and a bit more of a process for updating WASI tests, happy to help out with the generation part of the WASI tests, just ping me!

Can you update the wasi-tests subtree to latest master (with your fix added)?
