+Subject: [PATCH] Make sure PKGS= is propogated into the submake for "make
+ deps"
+
+When we're doing make deps with "$(CC) -MF", gcc and clang have different
+behavior, both broken in different ways, which we're hitting because of a
+missing -I argument for libefivar's includes. On clang, when a header can't
+be found, it emits a rule with the header as a prerequisite without a path,
+such as efivar.h here:
+
+efibootmgr.o: efibootmgr.c fix_coverity.h efivar.h efiboot.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/list.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/unparse_path.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efibootmgr.h \
+ error.h
+
+Then the build that utilizes that rule will fail to find the
+prerequisite and tell you something like:
+
+make[1]: *** No rule to make target 'efivar.h', needed by 'efibootmgr.o'. Stop.
+make[1]: Leaving directory '/home/pjones/devel/github.com/efibootmgr/master/src'
+
+With gcc, when a header can't be found, it emits a rule without that header
+as a prerequisite, as such (again with efivar.h):
+
+efibootmgr.o: efibootmgr.c fix_coverity.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/list.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/unparse_path.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efibootmgr.h \
+ error.h
+
+And then your build will fail if you haven't adjusted CFLAGS to tell it
+where to find the header.
+
+Both of these would be better just erroring, but at least gcc's doesn't
+insert a *wrong* dependency.
+
+This patch adds "PKGS=efivar efibootmgr popt" for all deps under src/.
+Technically that's overkill, as efibootmgr itself doesn't need popt, but it
+doesn't hurt anything to have the extra part there. The resulting
+.efibootmgr.d file has the prerequisites expressed correctly:
+
+efibootmgr.o: efibootmgr.c fix_coverity.h /usr/include/efivar/efivar.h \
+ /usr/include/efivar/efiboot.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/list.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/unparse_path.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efi.h \
+ /home/pjones/devel/github.com/efibootmgr/master/src/include/efibootmgr.h \
+ error.h
+
+This fixes the issue described in github PR #96
