Linux 3.15 adds support for clock_gettime, gettimeofday, and time vDSO (commit id 37c975545ec63320789962bf307f000f08fabd48). This patch adds GLIBC supports to use such symbol when they are avaiable. Along with x86 vDSO support, this patch cleanup x86_64 code by moving all common code to x86 common folder. Only init-first.c is different between implementations.
