Subject: [PATCH] COMPILING.md: Reduce dependencies when building protobuf

These changes avoid a dependency on automake, autoconf, and libtool. The
./configure script is only available via the release artifacts, not git.

For example, on Debian Buster only curl and build-essential need to be
installed.
