None known.
Workaround:
- If this happens for you, stick with glibc-2.6.1 for now.
- Or investigate! :-)

+Seemingly-native toolchains |
+----------------------------+
+
+Seemingly-native toolchains are toolchains that target the same architecture
+as the one it is built on, and on which it will run, but the machine tuple
+may be different (eg i686 vs. i386, or x86_64-unknown-linux-gnu vs.
+x86_64-pc-linux-gnu). This also applies if the target architecture is of the
+same kind (eg. x86 vs. x86_64, or ppc vs. ppc64).
+
+Such toolchain is tricky to build, as the configure scripts may incorrectly
+assume that files (headers and libs) from the build (or host) machine can be
+used by the cross-compiler it is going to build. The problem seems to arise
+only with glibc (and eglibc?) starting with version 2.7.
