linux: Implement pipe in terms of __NR_pipe2
The syscall pipe2 was added in linux 2.6.27 and glibc requires linux 3.2.0. The patch removes the arch-specific implementation for alpha, ia64, mips, sh, and sparc which requires a different kernel ABI than the usual one. Checked on x86_64-linux-gnu and with a build for the affected ABIs.
