+Subject: [PATCH] Add -lxml2 to linker cmdline of xml is found
+
+When cross compiling for systems where static libs
+for libxml are not available cmake's detection mechanism
+resort to linking with libxml.so but doesnt use -lxml2
+liblldbHost.a however requires libxml on linker
+cmdline _after_ itself so its use of symbols from libxml2
+can be resolved. Here check for libxml2 being detected and
+add it if its found.
+
+Fixes
+minifi-cpp/0.7.0-r0/recipe-sysroot-native/usr/lib/libxml2.so is incompatible with elf32-i386
+| clang-11: error: linker command failed with exit code 1 (use -v to see invocation)
