Ian Lance Taylor 2fdff9586b 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 .
