commit 7f2a5e368e54884b032982b5394b8ffc3ace5a8a Author: Anthony PERARD <anthony.perard@xxxxxxxxxx> AuthorDate: Mon Aug 22 12:09:07 2022 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Mon Aug 22 12:09:07 2022 +0200 tools: Introduce $(xenlibs-ldlibs, ) macro This can be used when linking against multiple in-tree Xen libraries, and avoid duplicated flags. It can be used instead of multiple $(LDLIBS_libxen*). For now, replace the open-coding in libs.mk. The macro $(xenlibs-libs, ) will be useful later when only the path to the libraries is wanted (e.g. for checking for dependencies).
