Remove socket.S implementation
This patch removes the socket.S implementation for all ports and replace it by a C implementation using socketcall. For ports that implement the syscall directly, there is no change. The patch idea is to simplify the socket function implementation that uses the socketcall to be based on C implemetation instead of a pseudo assembly implementation with arch specific parts. The patch then remove the assembly implementatation for the ports which uses socketcall (i386, microblaze, mips, powerpc, sparc, m68k, s390 and sh). I have cross-build GLIBC for afore-mentioned ports and tested on both i386 and ppc32 without regressions.
