Get the viewer launching on Fedora Asahi Remix

Media plugins enabling not yet.
OpenXR is disabled for now (it hasn't been used anyway).
perl-FindBin is needed to be able to build OpenSSL on Fedora aarch64.
Setting the C standard to 90 when building cURL is needed, otherwise
it would fail at configure time with a misleading error of not finding
link/run time requirements for dependencies (such as nghttp2 and zlib),
at least on Fedora (and macOS too back then, I remember).
GCC treated SSE2NEON warnings as errors on so many files,
so -Wno-cpp is added globally.
The same Linux CPU frequency calculation needs to be out of the x86 scope,
otherwise the viewer would complain about not meeting the requirements
at launch time.
