Illegal instruction on raspberry pi4
my environment is:
Raspberry pi4 8Gb
Os gentoo linux
All the packages required are installed

I compiled the code with:
`make -j4`
and I also tried as test
`make release-static-linux-armv8`
without errors.
the issue faces when I start the monero deamon:

```
2021-10-23 13:08:07.401 I Monero 'Oxygen Orion' (v0.17.2.3-7dbb0d1fc)
2021-10-23 13:08:07.401 I Initializing cryptonote protocol...

2021-10-23 13:08:07.403 I Loading blockchain from folder /root/.bitmonero/lmdb ...
Illegal instruction

```
I also tried the options `-DAES_NO=ON`, `MONERO_USE_SOFTWARE_AES=1` and `MONERO_RANDOMX_UMASK=8` with same Illegal instruction error.
After that, I tested the official monero version, master and also release-v0.17, and eithers run fine beginning the db sync.
How can I resolve the issue?
