GCC not GDB.

Never configure glibc with a prefix other than /usr. Configure with
--prefix=/usr and use install_root to install in a sysroot; configure the
compiler with that same sysroot.
In various places glibc's configuration checks for whether the prefix is
/usr and does special handling only if that is the case. Unless you use
--prefix=/usr you will get an installation that does not use the standard
Linux directory layouts and cannot be used as a basis for the root
filesystem on your target system compatibly with normal glibc
