### Description
I want to debug `Kamailio` using `GDB` and compiled sources on `aarch64` architecture
(`t4g` AWS instance).
But produces object files do not contain debug info.
Then executed
```
make -n
```
And found that no `-g` options used during compilation.
I have specified `CFLAGS` and `CPPFLAGS` but with wont help.
### Expected behavior
On all dist used `-g` compilation flag by default.
If I have specified `CFLAGS` and `CPPFLAGS` as environment variables, then these flags
used by GCC during compilation.
#### Actual observed behavior
`-g` flag do not used by default on `aarch64` architecture.
`CFLAGS` and `CPPFLAGS` as environment variables do not used during compilation time.
### Additional info
as hotfix I have used this patch
```diff

You can push this change to Makefile.defs, fine for me.

@sergey-safarov the logic for the "-g" flag for other architectures is a bit
different in the Makefile.def, and i am not sure if its maybe also need another extension
for this architecture.
Can you please quote the output of "kamailio -I" to this ticket?
