gcc-arm-none-eabi: what were the Newlib compilation options?

This question has been asked before, but ignored (https://community.arm.com/support-forums/f/compilers-and-libraries-forum/52220/gnu-arm-embedded-what-were-the-newlib-compilation-options).

I would dare to ask it again:

Exactly what compilation options were used to build Newlib?

The versions of GCC tools of interest are:

gcc-arm-none-eabi-9-2020-q2-update
gcc-arm-none-eabi-10.3-2021.10

It's not just an idle interest, or an attempt to waste your valuable time. I've got a practical need to rebuild Newlib as position-independent code, if you need to know why.

Is any real developer with access to build scripts reading this?

Thank you in advance,

Vadim Barshaw
