+Subject: [PATCH] dynload/dynload_unix.c: don't use RTLD_DI_LINKMAP with uclibc
+
+RTLD_DI_LINKMAP is not defined on uclibc so check that __UCLIBC__ is not
+defined before using it otherwise build fails on:
+
+dynload_unix.c:93:19: error: 'RTLD_DI_LINKMAP' undeclared (first use in this function); did you mean 'RTLD_BINDING_MASK'?
+   if(dlinfo(pLib, RTLD_DI_LINKMAP, &p) == 0) {
+                   ^~~~~~~~~~~~~~~
+                   RTLD_BINDING_MASK
