+    rt: Turn forwards from librt to libc into compat symbols [BZ #24194]
+    
+    As the  result of commit 6e6249d0b461b952d0f544792372663feb6d792a
+    ("BZ#14743: Move clock_* symbols from librt to libc."), in glibc 2.17,
+    clock_gettime, clock_getres, clock_settime, clock_getcpuclockid,
+    clock_nanosleep were added to libc, and the file rt/clock-compat.c
+    was added with forwarders to the actual implementations in libc.
+    These forwarders were wrapped in
+
+    #if SHLIB_COMPAT (librt, GLIBC_2_2, GLIBC_2_17)
+    
+    so that they are not present for newer architectures (such as
+    powerpc64le) with a 2.17 or later ABI baseline.  But the forwarders
+    were not marked as compatibility symbols.  As a result, on older
+    architectures, historic configure checks such as
+    
+    AC_CHECK_LIB(rt, clock_gettime)
+    
+    still cause linking against librt, even though this is completely
+    unnecessary.  It also creates a needless porting hazard because
+    architectures behave differently when it comes to symbol availability.
