I expect that even if this build gets deferred to when the testsuite is 
run, you'll still need to use $(libunwind) (given that all the links done 
in glibc build and testing are explicitly using -nostdlib then listing the 
required libraries, to avoid any pre-existing system libc getting 
involved, so you're losing GCC's built-in knowledge of when to use 
-lunwind).
