kbuild: fix header installation under fakechroot environment
Since commit fcc8487d477a ("uapi: export all headers under uapi directories") fakechroot make bindeb-pkg fails, mismatching files for directories: touch: cannot touch 'usr/include/video/uvesafb.h/.install': Not a directory This due to a bug in fakechroot: when using the function $(wildcard $(srcdir)/*/.) in a makefile, under a fakechroot environment, not only directories but also files are returned. To circumvent that, we are using the functions: $(sort $(dir $(wildcard $(srcdir)/*/)))) Fixes: fcc8487d477a ("uapi: export all headers under uapi directories") Signed-off-by: Richard Genoud <> Signed-off-by: Masahiro Yamada <>
