Older versions of git included in older linux distributions are not able
to download source from Github. A newer version is required with a newer
OpenSSL. This requires to also build curl with the same OpenSSL.
CMake is downloaded precompiled if available (64bits system) or compiled
from source otherwise.

To accommodate the requirements associated with x86 and x64 images, the
command building OpenSSL and CMake became overly complex and hard to
maintain.
This commit has multiple purposes:
(1) simplify common.docker
(2) fix the building of 64-bit shared libraries against the static openssl
libraries by passing the -fPIC flag.
(3) ensure [many]linux-x86 and [many]linux-x64 images have an up-to-date
OpenSSL install. Openssl static libraries are installed in /usr
(4) simplify and speedup CMake build avoiding the second build with
explicit -DCMAKE_USE_OPENSSL:BOOL=ON. Indeed, configuring CMake on Linux
already looks for OpenSSL.
(5) speedup download of CMake source directly downloading the archive
corresponding to the revision.
(6) test CMake by:
- running CMake.FileDownload test
- trying to download a file served over https
This commit fixes the following error reported when building the base
image.
sh: 1: [: =: unexpected operator
sh: 1: [: =: unexpected operator
It turns out that (1) DEFAULT_DOCKCROSS_IMAGE is not set when building the
base image and (2) latest openssl will not be available in linux-x64 and
linux-x86 images.
