Failed build: failed checks on defined-symbols.txt, undefined-symbols.txt

Building on: Arch Linux x64 using system llvm and clang.
Build steps:
Checkout main branch of wasix-libc
Patch the getpid error as mentioned in #4
Run: TARGET_ARCH=wasm32 TARGET_OS=wasix make CC=clang AR=llvm-ar NM=llvm-nm
Result: the sysroot builds, but then some post checks on (un-)defined symbols fail. I am not sure if it is a real issue, since there are more defined symbols than expected, and less undefined symbols.
