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 
installations.
