It happens on every platform I configure, but if you want something specific:
--build=i686-unknown-linux-gnu --host=i686-unknown-linux-gnu
--target=x86_64-unknown-linux-gnu

I also have the same problems on:
--build=i686-unknown-linux-gnu --host=i686-unknown-linux-gnu
--target=mips64-unknown-linux-gnu

and:
--build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu
--target=powerpc-unknown-linux-gnuspe

This is a build from crosstool-ng. --enable-symvers=gnu is set staticly in:
http://crosstool-ng.org/hg/crosstool-ng/file/tip/scripts/build/cc/gcc.sh

> * why do you insist on specifying the symvers flavor manually?

"I" didn't insist on specifying it manually. crosstool-ng did.
While you might say that is a problem with crosstool-ng, but the older
crosstool and other cross tool scripts use this as well.

If every other component besides libjava specifically check for
yes|no|gnu*|sun, why doesn't libjava?

Or...

If I shouldn't use --enable-symvers=gnu, shouldn't all other components fail to
support it?
