Raspberry Pi OS • Compiling libopus 1.5.1 with Linux fails on latest Raspberry Pi OS

I already had a long discussion with the lead developer on Github:
https://github.com/xiph/opus/issues/323 ... 2005178844

CC silk/arm/NSQ_del_dec_neon_intr.lo
silk/arm/NSQ_del_dec_neon_intr.c: In function ‘silk_NSQ_del_dec_neon’:
silk/arm/NSQ_del_dec_neon_intr.c:424:55: warning: iteration 80 invokes undefined behavior [-Waggressive-loop-optimizations]

silk/arm/NSQ_del_dec_neon_intr.c:423:18: note: within this loop
423 | for( ; i < NSQ_LPC_BUF_LENGTH; i++ ) {

After "make install" I use "opusenc -V" to check the library in use and I find the previous one.

I repeated the operation with different versions of Linux and other SBCs and I can only assume that the warnings above do not lead to the correct installation of opuslib 1.5.1.

ldd /usr/bin/opusenc
linux-vdso.so.1 (0x0000003fa3b11000)
libopusenc.so.0 => /lib/riscv64-linux-gnu/libopusenc.so.0 (0x0000003fa3aee000)
libopus.so.0 => /usr/local/lib/libopus.so.0 (0x0000003fa3aa1000)

libc.so.6 => /lib/riscv64-linux-gnu/libc.so.6 (0x0000003fa38b8000)
/lib/ld-linux-riscv64-lp64d.so.1 (0x0000003fa3b13000)
libogg.so.0 => /lib/riscv64-linux-gnu/libogg.so.0 (0x0000003fa38af000)

Is it possible that it depends on your Debian-derived distribution?
