bug: cannot compile crypto code for bare metal using Go 1.24

[deadprogram]

When using Go 1.24, some code with bare metal targets cannot build. The same code appears to build fine in Go 1.23.x

For example, the drivers lorawan/atcmd example. See tinygo-org/drivers#744

I confirmed that this issue also applies to other code using crypto packages running on bare metal targets. For example hybridgroup/tinygo-tkey#2
