cmd/compile: allow duplicate DWARF producer symbols
When building test binaries, we build one archive with all of the test sources and a second archive with the generated test package main and link them together. If the test sources are themselves in package main and the test was compiled with non-default compiler flags, then both archives will contain a go.cuinfo.producer.main symbol, leading to a duplicate symbol failure. This has been causing test build failures on darwin-arm-a1428ios, darwin-arm64-a1549ios, linux-amd64-noopt, android-arm-wiko-fever, and android-arm64-wiko-fever since CL 71430 added this symbol. This CL should fix the build.
