Building python shared libraries using libtool

[Albert Chin]

It's currently impossible to build a .so using libtool for Python
because of -bnoentry. If an entry point is specified with
-Wl,-e[label], it won't be honored because -bnoentry is last on the
command-line. Python .so files need -Wl,-e[label] on AIX. So, I
propose we move -bnoentry before $compiler_flags with the attached
patch against HEAD.

Any objections?

BTW, why do we even use -bnoentry?

        * m4/libtool.m4: Move -bnoentry linker option before
        $compiler_flags to honor any possible -e entries in
        LDFLAGS.
