I have now done such testing, applying the patch on top of my current
working tree, which is not completely up-to-date (working on that next),
but that shouldn't matter.  Native building/testing continues to work as
before, as does bootstrapping a i686-linux-gnu to i686-gnu
cross-compiler.

For the latter indeed a fake libgcc_eh.a does not need to be created
anymore before building glibc.  I can now do: binutils, GCC »configure
--disable-shared --disable-threads --without-headers --with-newlib« »make
all-gcc install-gcc all-target-libgcc install-target-libgcc« [fake
libgcc_eh.a was created here], GNU Mach headers, MIG, GNU Hurd headers,
libpthread headers, glibc, GNU Hurd libraries, libpthread, complete GCC,
glibc again (which now probably no longer is necessary anymore).

 Thomas
