assembly code fails the build

[chrislusf]

There are some assembly code related to poll deadline. Can they be changed to pure Go?

$ go version
go version go1.16 darwin/amd64

$ go install
/usr/local/go/pkg/tool/darwin_amd64/link: running clang failed: exit status 1
Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
