install-containerd-static: use netgo buildtag
When compiling containerd binaries statically, linker rightfully
complains:
+ make BUILDTAGS=static_build 'EXTRA_FLAGS=-buildmode pie' 'EXTRA_LDFLAGS=-extldflags "-fno-PIC -static"'
🇩 bin/ctr
# github.com/containerd/containerd/cmd/ctr
/tmp/go-link-343047789/000000.o: In function `_cgo_b0c710f30cfd_C2func_getaddrinfo':
/tmp/go-build/net/_obj/cgo-gcc-prolog:46: warning: Using 'getaddrinfo'
in statically linked applications requires at runtime the shared
libraries from the glibc version used for linking
The same error appears for ctr, containerd, and containerd-stress
binaries.
The fix is to use Go's own DNS resolver functions, rather than
glibc's getaddrinfo() -- this option is turned on by `netgo` build tag.
See https://golang.org/pkg/net/ (look for "Name Resolution") for more
details.
