 use cmake_cxx_library_architecture to detect x86
 When building for x86 in a x86_64 host (e.g. with pbuilder) CMake
 will set CMAKE_SYSTEM_PROCESSOR to x86_64, and WebKit will assume
 that it's a 64-bit build. Let's use the C++ compiler architecture as
 a temporary solution to detect x86 correctly.

 use wtf_cpu_unknown when building for x32
 WebKitGTK doesn't build on X32 even with the JIT disabled.
 Treating the CPU as unknown is perhaps a bit severe, but it allows us
 to get the build done until someone steps up to maintain this
 properly.

 force the single-process mode in evolution and geary
 Since WebKitGTK 2.26 the single-process mode is considered a security
 risk and the process limiting APIs have been completely disabled.
 This change is transparent for most applications, but Geary and
 particularly Evolution (see upstream bug #587) are known to have
 problems in multi-process mode. This has already been fixed in Geary
 3.33.91 and in Evolution 3.34.1.
 .
 Although the API to set the single-process model is no longer
 available, it is still possible to do it internally. This patch does
 that for Evolution and Geary.
 .
 This is a temporary workaround and it is especially meant for stable
 distributions and security updates, where patching or updating the
 affected apps is not an option.
