Doing so, besides (hopefully) adding clarity (not the least by way of using pattern rules where possible), also avoids explicit recursive $(MAKE) invocations. For xen-syms move re-usable helper rules to a new scripts/Makefile.link. While doing so, re-order .map file creation (which can in principle fail) and check-endbr.sh invocation ahead of putting in place the final image (which is now the result of a simple rename). Also drop --source-name= from the tools/symbols invocation which has --empty passed, for being meaningless there. Signed-off-by: Jan Beulich <jbeulich@suse.com>
