opusfile: fix building for Android with http=True

[kambala-decapitator]

Summary

Changes to recipe: opusfile/all

Motivation

Fixes building opusfile with http=True for Android

Details

Build fails due to using C99 features but compiling in C89 mode. I've opened issue in upstream xiph/opusfile#52 as I'm not sure what's the right way to proceed here (if I can blindly replace 89 with 99). In the recipe I replace 89 with 99 only for Android (because again I'm not sure if there will be any side effects on other platforms).

@kambala-decapitator Hello! 👋

Thank you for pushing PR and alerting the upstream about the case. Indeed I could reproduce your scenario: opusfile-0.12-android-error.log

And when applying your patch, it works normally for Android: opusfile-0.12-android-patched.log

I did a small change in your PR to accept settings.compiler.cstd in case defined in the profile.

I found another related issue in the upstream: xiph/opusfile#44

And as you pointed, the C99 is needed due function inline feature.

Thanks @uilianries for providing the build logs - good for traceability.

the issues are in the Linux headers (the android Linux headers) - not the library itself.

This library appears unmaintained in terms of releases and maintainers acknowledging issues - and under those circumstances, I would discourage use
