Cherry Mui 5ef9566694 [release-branch.go1.16] cmd/link: force eager binding when using plugins on darwin 
When building/using plugins on darwin, we need to use flat
namespace so the same symbol from the main executable and the
plugin can be resolved to the same address. Apparently, when using
flat namespace the dynamic linker can hang at forkExec when
resolving a lazy binding. Work around it by forcing early bindings.

Updates #38824.
Fixes #50245.
