aix: add initial platform support for aix using gcc/gxlc

Adds initial libuv build/platform support for AIX. Builds work using gcc or the
IBM XL C compiler using its gxlc wrapper. Platform support is added for
uv_hrtime, uv_exepath, uv_get_free_memory, uv_get_total_memory, uv_loadavg,
uv_uptime, uv_cpu_info, uv_interface_addresses.
