[PATCH, regression?] Support --static-libstdc++ with native AIX ld

[Michael Haubenwallner]

Hi,

attached patch actually makes gcc-4.8 useable after removing builddir when 
using native AIX ld,
as libstdc++ now really is statically linked into xgcc/xg++, like with other 
platforms or with
GNU binutils on AIX.

This also renders those tries/patches needless that drop the 
RPATH_ENVVAR=LD_LIBRARY_PATH on AIX.

Thank you!

    AIX ld does support -bstatic/-bdynamic instead of -Bstatic/-Bdynamic.
    * gcc/configure.ac (gcc_cv_ld_static_dynamic): Define for AIX native ld.
    * gcc/configure: Regenerate.
