ossp-uuid, libffi, libgcrypt: Pass --tag=CC option to libtool
libtool tries to guess the --tag value based on CC/CXX environment variables and the compile commandline generated by makefiles. This heuristics however fails when we construct CC variables in OE and add security flags to it, especially -fPIE -pie which are added by external compilers e.g. clang particularly. It fails because libtool removed PIE flags from compiler cmdline intelligently if it figures out that its building a library, which means that the CC variable passed from cmdline does not match with the compiler cmdline constructed by libtool and we end up with errors like | arm-bec-linux-musleabi-libtool: compile: unable to infer tagged configuration | arm-bec-linux-musleabi-libtool: error: specify a tag with '--tag' This works with internal gcc toolchain because we configure gcc for PIE when hardening is selected and dont pass -fPIE -pie options explicitly but this is not an option for clang, and some external gcc toolchains using older gcc This patch adds the --tag option to help libtool set correct tags in packages where it cant get it right via its heuristics Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
