Where do I find a working example of configuring and compiling the Opus codec library on a Linux machine for an STM32F407 target?

[DBust.1]

Something along the lines of: ./configure CFLAGS="-O2 -mfpu=neon -mthumb -mcpu=cortex-m4" LDFLAGS="--specs=nosys.specs" --host=arm-none-eabi --disable-rtcd --enable-fixed-point

Still having issues with make errors, e.g.,

celt_pitch_xcorr_arm-gnu.S:547: Error: thumb conditional instruction should be in IT block

Determine if the assembler source file contains any conditional assembly code, and what command line defines those would need, or if you need to find a different source file for the Cortex-M devices.
