log from sed that shows __redirect_alloc_fd failure

If file descriptor 1023 is open on SVR4, then /dev/fd/{0..1023} will exist, regardless of whether or not any other file descriptors are open. The fallback in __redirect_alloc_fd assumes that the existence of /dev/fd/* implies an open file descriptor. This causes a build failure on Open Indiana 151a7 because it ships with bash 4.0.28, file descriptor 1023 is somehow opened during the bootstrap and __redirect_alloc_fd cannot find a free file descriptor. Oracle's documentation suggests that you should check for free file descriptors by opening them and checking for an error:

Unfortunately, I cannot figure out how to do this from the shell.
