Pass -w to the Go linker to reduce binary size while retaining the
symbol table for tools that inspect Go binaries.
For a linux/arm64 build, this reduces the CLI binary from 39,809,791
to 31,310,197 bytes: a saving of 8.5 MB (21.4%).
Place the default before caller-supplied GO_LDFLAGS so builds can
retain DWARF by passing GO_LDFLAGS="-w=0".
