Corresponding source code
Even if libintl.h has not changed, the libintl.a that is being installed at the same time may have changed. Therefore relinking of the libraries or executables that make use of libintl.a may be needed, but the compiler has no way to know it, because the Makefile rules typically do not have the .a files as dependencies, and AFAIK gcc's dependency mechanism looks at the included .h files, not at the linked .a files.
Therefore, really, the only reliable behaviour is that libintl.h and libintl.a are being considered "new", thus your project gets recompiled.
I guess that's also the reason why the install(1) program does not have an option to skip installation if the contents won't change.
