* Factorize info into new verbose file. Refactor Makefile, global, cpp11*. Add Linux32-clang * Display used config with POCO_VERBOSE * Add cross compilation toward x86 with host amd64 * Refactor config names * Add lib32gcc runtime * Add g++-5-multilib * Use OSARCH=i386 for OSX x86 * Avoid building Crypto since OpenSSL is only x64 on OSX * Avoid building Crypto since OpenSSL is only x64 * Avoid Data/* on cross compilation to x86 * Add gcc-5-multilib to clang 4.0 x86 * Ignore TimerTest on OSX for now. * Cleanup * Add other set of TimerTest. * New test that fails on OSX
