cmd/go: always use --whole-archive for gccgo packages This is, in effect, what the gc toolchain does. It fixes cases where Go code refers to a C global variable; without this, if the global variable was the only thing visible in the C code, the generated cgo file might not get pulled in from the archive, leaving the Go variable uninitialized. This was reported against gccgo as https://gcc.gnu.org/PR68255 .
