Golang go/internal/gccgoimporter: go building failing with gcc 14.1.0 [1.21 backport]

@ianlancetaylor requested issue #67846 to be considered for backport to the next 1.21 minor release.

@gopherbot Please open backport issues.

This is due to some changes in gccgo that appeared in GCC 14. To fix this we will need to backport https://go.dev/cl/537195. That change is small and safe. This is already fixed at HEAD.
