[Bug libc/10422] New: eventfd/signalfd do not work with < 2.6.27 kernel

eventfd/signalfd were working correctly up to glibc 2.8. Starting with glibc
2.9, glibc 2.10 and git version, a glibc compiled against >= 2.6.27 kernels
headers has non functional eventfd/signalfd when used on < 2.6.27 kernels. The
reason is the inconditional use of the new syscall without trying the old
syscall.
Note that the 2.6.27 kernel version correspond to the one on x86_64, it varies
a bit depending on the architecture.
Patch will follow.
