-Subject: [PATCH] BUG/MEDIUM: tools: fix build with static only toolchains
-
-uClibc toolchains built with no dynamic library support don't provide
-the dlfcn.h header. That leads to build failure:
-
- CC src/tools.o
-src/tools.c:15:10: fatal error: dlfcn.h: No such file or directory
- #include <dlfcn.h>
- ^~~~~~~~~
-Enable dladdr only when USE_DL is defined.
