License terms for a newlib source file

[Jens Wiklander]

Hi,

I'm working on an open source project with BSD license (OP-TEE
https://github.com/OP-TEE/optee_os) where we have imported some parts
of newlib. To make it clear for end users we're including the exact
license and copyright of each file in our project at the beginning of
each file.

Can you help me with license and copyright for libc/machine/arm/setjmp.S?

Thanks,
Jens
