In
commit ba78db44f6532d66a1e704bd44613e841baa2fc5 Author: Daniel P. Berrange <berrange@redhat.com> Date: Wed Jan 25 16:14:10 2017 +0000
make: move top level dir to end of include search path
The dir $(BUILD_DIR)/$(@D) was added to the include path. This would sometimes point to a non-existant directory, if the sub-dir in question did not contain any target-independant files (eg tcg/). To deal with this the rules.mak attempted to create the directory.
While this was succesful, it also caused accidental creation of files in the parent of the build dir. e.g. when building common source files into target specific output files.
Rather than trying to workaround this, just revert the code that attempted to mkdir the missing include directories. Instead just turn off the compiler warning in question as the missing dir is expected & harmless in general.
NB: you can clean up a build directory parent that has been filled with empty directories by commit ba78db44f653 using this GNU find command in that parent directory: find audio backends block chardev crypto disas fsdev hw io linux-user \ migration nbd net qapi qom replay slirp target ui util \ -type d -empty -delete
