What did you do?

I tried to compile libGoReSym with c-achived mode in the mips64le (loongnix) platform, but found the following error：
/opt/go/bin/go build -buildmode=c-archive -o libGoReSym.a

internal/itoa

compile: linux/mips64le does not support -shared
。。。

The program is C wrapper for GoReSym

What did you expect to see?

-buildmode=c-achived support on linux/mips64le

What did you see instead?

-buildmode=c-achived not support on linux/mips64le

Although the problems of c-achived and c-shared are very similar, and the error messages are similar, . But they are indeed not the same problem, I just confirmed the issue with longson's R&D.

There is a stack of changes starting at https://go.dev/cl/348732 that may fix this.

A stale stack of changes, sadly.
