Libraries present on the CI runner system might affect the released
binaries. Specifically, the MacOS runner in GitHub has librtsp, libidn2
and zstd installed, which makes curl link against them.
Explicitly disable these linking, as we want to keep the precompiled
binaries in our releases with minimal requirements. A user wishing to
use these specific features can build from source on a system with these
libraries present.
Add support for cross-compiling curl-impersonate.
Cross compiling can now be done using the '--host' flag to the configure
script. This will make sure that all sub-components are cross-compiled.
In addition, compiling for a different system requires explicitly
specifying multiple paths used by curl (e.g. for certificates). These
options were added to the configure script as well.
The build and test CI workflow will now attempt to cross-compile
curl-impersonate to ARM64 (aarch64), and upload this binary to the
GitHub release page.
Add the 'configure' script generated by autoconf and its dependencies to
the repository to save the users from having to run 'autoconf' manually.
