To avoid that, use the --with-glibc-version= option when configuring a bootstrap GCC to be used to build glibc. Mainline glibc's build-many-glibcs.py knows how to configure GCC and glibc for building many different configurations. It uses --disable-libsanitizer, but if libsanitizer is meant to work for all glibc configurations you could try removing it (adding it back for the initial bootstrap GCC only) and seeing what libsanitizer problems it shows up.

Joseph, thank you for clarification. Anyway, the failure is confirmed. I suspect it was caused by this commit in Glibc: ommit a059d359d86130b5fa74e04a978c8523a0293f77 Author: David S.

Attached patch fixes build error (perhaps all sparc stuff should go upstream, because I think we already have too many local fixes?).
