Description
The new Xcode 6.3's clang 6.1 (3.6.0svn) compilers break the bootstrap of FSF gcc 4.9.2 and gcc 4.9.3svn due to configure leaving BUILD_CONFIG unset.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65733 https://llvm.org/bugs/show_bug.cgi?id=23192
This same issue occurs when the llvm 3.5.1, 3.5.2 or 3.6.0 compilers are used to bootstrap gcc. The current workaround is to explicitly pass --with-build-config=bootstrap-debug to configure when the newer clang compilers are in use.
