ARM support for app_rtsp_sip

[tommyjlong]

Hi @felipecrs
I see you just added a patch to include a couple of #defines for the app_rtsp_sip.c for ARM based builds.
Just checking in to see if these built OK.

A couple of things too:
Here it was mentioned that the builds failed on:
aarch64, armhf and armv7
but looks like the build dependency is arm*; maybe need to add aarch64?

When I was working on this problem back in 2022, I also added a third #define
#define ARM
I'm not sure why, but if the arm architectures build without it, then probably OK to leave it out.

The compilation worked fine for all the three ARM platforms, but I did not test yet.

Btw TARGETARCH should be arm64 rather than aarch64, that's why arm*.

Good to hear!

v4.2.0 is to be released soon and should include it (@los93sol is also waiting for it - #311)

BTW I'm dropping support for armhf (#315), please chime in if you have any concern.

I'm closing this issue, but there's no problem to continue discussing it.
