Patch 3 of 10 attached ...
The test for being able to dlopen yourself is flawed. It was using
$link_static_flag, which is only present in the generated libtool.
During autoconfiscation, the variable is called $lt_prog_compiler_static.
This was causing false positives becuase -Bstatic/-static were not being
passed through to the link editor, and thus we were actually testing
a dynamic a.out. Since $lt_prog_compiler_static most likely uses $wl,
ensure that wl is set to $lt_prog_compiler_wl before running the test,
so that $lt_prog_compiler_static expands correctly.

        * libtool.m4(AC_LIBTOOL_DLOPEN_SELF): Set wl if its not already
        set so expansion of export_dynamic_flag_spec works.
        Use lt_prog_compile_static, not link_static_flag.
