Makes sense. Are you saying that for static libraries, one has to redo
ranlib after strip?

And you're also saying that a "default strip", invoking strip without
any options, is the same as strip --strip-all?
I wonder if one can persuade the install program to do the right thing.
It should be straightforward to use separate variables
INSTALL_STATIC_LIB and INSTALL_SHARED_LIB, to override in the
install-strip target. But it seems overriding the strip command, e.g.,
to use strip --strip-unneeded, is going to be messy.
For install-sh, is one can set STRIPPROG="strip --strip-unneeded". For
GNU /usr/bin/install, one can set STRIPPROG="strip --strip-unneeded" in
the environment (untested, not sure if it is passed to the shell to
split into command and arguments). But that won't work with BSD install.
Checking on freebsd, it seems it checks an environment named STRIPBIN,
(not sure if there's also a BSD strip not accepting GNU options; on my
closest freebsd system, /usr/bin/strip is an ancient GNU binutils).
Since install-strip is an optional thing, I think I'd be happy to
support only the most mainstream cases here.
The alternative to using install -s would be to produce additional files
in the build directory, e.g., libnettle.a.stripped and install that. But
having that done as part of make install-strip breaks the expectation
that install targets shouldn't create or modify any files in the build
tree, and producing them in make all doesn't seem quite right either.
A third alternative is to have the install-strip target do things like
$(INSTALL_DATA) libnettle.a $(DESTDIR)$(libdir)
strip --strip-debug $(DESTDIR)$(libdir)/libnettle.a
ranlib $(DESTDIR)$(libdir)/libnettle.a # Rebuild index
and use install -s *only* for (non-script) executables.
