The fd_set size should not be an issue at all, since it's currently stored in a single unsigned long, given that 20 file descriptors is the max file descriptors per process (unless specially reconfigured). |

This enables elksemu to run ELKS binaries with networking system calls.
There is one significant difference from the standard Linux API: fd_set is contains only 64 file descriptors instead of 1024 descriptors. This is because the ia16-gcc binary I used FD_SETSIZE = 64, but if ELKS currently supports more file descriptors, this can be easily updated.
