+Use eventfd() function with uClibc
+
+The Boost eventfd code either directly makes the eventfd system call
+using __NR_eventfd (when __GLIBC_MINOR is less than 8), or otherwise
+uses the eventfd() function provided by the C library.
+
+However, since uClibc pretends to be glibc 2.2, the Boost eventfd code
+directly uses the system call. While it works fine on most
+architectures, it doesn't on ARC since __NR_eventfd is not defined on
+this architecture. However, eventfd() is properly implemented.
+
+So, this patch adjusts the logic used by Boost to consider uClibc as a
+C library providing the eventfd() function.
