Ok, inside the patch file now rather than at the end of the mail text.
I'm still unsure if the patch should contain a real ChangeLog diff or
a simple comment, as I doubt the ChangeLog diff would apply smoothly.

It is not me using --static-libstdc++, but gcc itself when linking xgcc/xg++.
Since switching to C++ inside gcc, it isn't possible to get working gcc/g++
binaries installed using native ld on AIX without this patch, as these need
dynamic libstdc++.a from builddir(!). Even after successful build with the
workaround from PR55105[1], installed binaries break when removing builddir.
Since --disable-build-with-cxx/--disable-build-poststage1-with-cxx [2] aren't
supported any more too, this really feels like a regression with 4.8.

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