knows that the eventual host link command must include the -lm
argument, so that the host linker will be able to find 'sin' in the
math library.

cmd/link Command Line Interface

The go command and any other Go-aware build systems invoke cmd/link
to link a collection of packages into a single binary. By default, cmd/link will

A future version of Go may change the defaults to
`tarinsecurepath=0` and `zipinsecurepath=0`.

Go 1.20 introduced automatic seeding of the
[`math/rand`](/pkg/math/rand) global random number generator,
controlled by the [`randautoseed` setting](/pkg/math/rand/#Seed).

Go 1.20 introduced the concept of fallback roots for use during certificate verification,
