AFAIS it is fixed by this for x86/glibc usage, at least here:
(There is much more from toolchain.eclass that we want.)

...
    strip-flags

    ${S}/configure ${conf} \
        || die "configure failed!"

    make \
        BOOT_CFLAGS="${CFLAGS}" \
        LDFLAGS="-Wl,-O1" \
        LIBPATH="/opt/${PN}-${SLOT}/lib" \
        STAGE1_CFLAGS="-O" \
        profiledbootstrap \
        || die "make failed!"
...

Btw, I changed this to take effect now:

-	--with-languages=java
+	--enable-languages=c,c++,java

This stops objc to build.
We want language c for bootstrapping stuff.
Fixes that error?!

lib/libgcj.so.7.0.0 still links to libgcc_s.so.1 from system gcc.

I do not like to see that. But, however, the more we copy
from toolchain.eclass it may change.
