tools/elfutils: use conditional to block build of shared objects
Add a potentially upstream-friendly conditional using the libtool configure variable "enable_shared" in order to block building and installing of shared objects and adjust the build of static libraries instead of directly patching lines in or out. Signed-off-by: Michael Pratt <mcpratt@pm.me> Link: https://github.com/openwrt/openwrt/pull/15690 Signed-off-by: Robert Marko <robimarko@gmail.com>
