Without regard to the specific proposed patch, I think the principle of 
linking them to use the newly built glibc directly is good.

I think we should go further (in several incremental steps) and actually 
have the testsuite run the tests directly (except for a few that verify 
that running them via executing the dynamic linker itself does work), 
since that's how people will generally use normal programs built with 
glibc.  And I'd also have the testsuite setup install glibc into a staging 
directory within the build directory, then link and run tests using that 
copy in which the various files are located relative to each other in the 
same way they would be after actual installation of glibc, to make the 
test environment still closer to that for normal user programs linked with 
glibc (and further simplify the command lines needed to build / run 
programs).
