Ok, here is what happens: This failure is only reproducible with the following config options: --disable-shared-glapi --disable-gles1 --disable-gles2 Which makes it pretty obvious what is to be blamed here. With those options set no installable libraries will be build below src/mapi, the only target is a static glapi.la. As lib_LTLIBRARIES is empty in that case the install-mesa-links target has no dependencies and gets executed immediately. This fails as it races with the compilation to create the .libs dir. As the install-mesa-links target works perfectly fine with an empty lib_LTLIBRARIES the fix is simply to not depends on the .libs directory for the state file of this target. A patch is on the list.
