After building with CONFIG_FORTIFY_SOURCE=y, many .*.d files are left
in lib/test_fortify/ because the compiler outputs header dependencies
into *.d without fixdep being invoked.
When compiling C files, if_changed_dep should be used so that the
auto-generated header dependencies are recorded in .*.cmd files.
Currently, if_changed is incorrectly used, and only two headers are
hard-coded in lib/Makefile.
