What problem is this solving?  Each configure option adds to the 
combinatorial explosion of poorly-tested different ways to configure 
glibc, so there needs to be strong justification for adding a new option 
(and increasing the minimum supported version of build tools can often be 
preferred to having conditionals to support older tools, depending on how 
widespread the older tools are).

If a new option is added, it needs documenting in install.texi and INSTALL 
needs to be regenerated.
