This was exposed with the stock Open64 build:
To give a concrete example, here are transcripts involving rebuilding
the Fortran runtime:
Without this patch touching a header file, nothing gets rebuilt:
$ touch
/scratch/dgilmore/sot-pp1/bo/osprey/../../osprey/libu/ffio/layer_def.h
$ make BUILD_TARGET=X8664 BUILD_COMPILER=SELF
BUILD_AREA=/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2 MACHINE_TYPE=X86_64
BUILD_ABI=I64BIT BUILD_ARCH=X8664 BUILD_HOST=IA32 BUILD_OPTIMIZE=DEFAULT
BUILD_TYPE=SHARED
make first
make[1]: Entering directory
`/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/libfortran'
MAKE
/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/libfortran//scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/include
make[1]: Leaving directory
`/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/libfortran'
make libfortran.a libfortran_p.a libfortran.so
make[1]: Entering directory
`/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/libfortran'
make[1]: `libfortran.a' is up to date.
make[1]: `libfortran_p.a' is up to date.
make[1]: `libfortran.so' is up to date.
make[1]: Leaving directory
`/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/libfortran'
make last
make[1]: Entering directory

make[1]: Leaving directory
`/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2/libfortran'
With this patch I am seeing reasonable rebuild behavior:
$ touch
/scratch/dgilmore/sot-pp1/bo/osprey/../../osprey/libu/ffio/layer_def.h
$ make BUILD_TARGET=X8664 BUILD_COMPILER=SELF
BUILD_AREA=/scratch/dgilmore/sot-pp1/bo/osprey/targdir_lib2 MACHINE_TYPE=X86_64
BUILD_ABI=I64BIT BUILD_ARCH=X8664 BUILD_HOST=IA32 BUILD_OPTIMIZE=DEFAULT
BUILD_TYPE=SHARED
