+Fixes three issues:

+   (musl/uclibc) ld.so to satisfy NEEDED dependency inserted by
+   -ljvm. Fix to not link against -ljvm, and disable -z defs so
+   undefined symbols are allowed in sos
+ - the previous makes ldd generate errors on unresolved symbols (musl)
+   remove it altogether as it's used for informative purposes only
+   (display things - not check anything useful)
+ - Don't delete the generated directory $(GENCSEXT), this can
+   confuse make in highly parallel builds with:
