+# Make sure these are used to build the libc.so shared object too.  There

+# functions like memcpy and mach_msg).  This works out fine at run time
+# (all the objects are loaded before resolving their symbols, so these
+# interdependencies are fine).  But to create the shared objects we must
+# link them one at a time; since each needs one or both of the others to
+# produce its DT_NEEDED entries and to assign its undefined symbols the
+# right symbol versions, we can't do any of them before the others!  To
+# get around this, we link each lib*user.so shared object twice.  First,
+# we link an object without reference to libc.so (since we haven't linked
+# libc.so yet), so it lacks a DT_NEEDED record for the libc soname it
+# depends on, and its undefined symbol references lack the symbol version
+# assignments they should have.  We will use this shared object solely to
+# link libc.so against it; that gives libc.so the proper DT_NEEDED record,
+# and symbol versions assignments (if the lib*user.so object is using them).
+# Finally we link a second version of the same lib*user.so shared object,
+# this time linked normally against libc so it gets a proper DT_NEEDED
+# record and symbol version set; this one can be installed for run-time use.
