Sorry, was svr4, not srv4

This is weird!

I'm trying to undestand the libtool script. Looks like the -brtl
should have some behaviour changes.
On newer libtool even svr4 should do the work (use .so files instead of .a).

I found this comment in libtool

        # Test if we are trying to use run time linking or normal
        # AIX style linking. If -brtl is somewhere in LDFLAGS, we
        # have runtime linking enabled, and use it for executables.
        # For shared libraries, we enable/disable runtime linking
        # depending on the kind of the shared library created -
        # when "with_aix_soname,aix_use_runtimelinking" is:
        # "aix,no"   lib.a(lib.so.V) shared, rtl:no,  for executables
        # "aix,yes"  lib.so          shared, rtl:yes, for executables
        #            lib.a           static archive
        # "both,no"  lib.so.V(shr.o) shared, rtl:yes
        #            lib.a(lib.so.V) shared, rtl:no,  for executables
        # "both,yes" lib.so.V(shr.o) shared, rtl:yes, for executables
        #            lib.a(lib.so.V) shared, rtl:no
        # "svr4,*"   lib.so.V(shr.o) shared, rtl:yes, for executables
        #            lib.a           static archive
