[PATCH] [PORTABILITY] don't use nonstandard __fpending in nohup

[Rich Felker]

this patch may be controversial but it both reduces size and allows
building without using the nonstandard glibc-internal __fpending
function. i'm not sure whether the semantics are correct but EBADF
should only happen under very limited conditions.
