Subject: [PATCH] compiler: explicitly disable PIC in wasm32 NCG
This commit explicitly disables the ncgPIC flag for the wasm32 target.
The wasm backend doesn't support PIC for the time being.
(cherry picked from commit 87e34888bca31b8fe5c860e2c52ef1e622a501de)
(cherry picked from commit f46220a91f1c44194c5f537d2285b3284d1403cb)
