This has broken the testsuite build for all cross-compilation situations 
not running the newly built tests.  You can't run a program built with the 
new glibc unless $(run-built-tests) is yes.  Either disable everything 
depending on running these programs unless $(run-built-tests) is yes or 
revert the commits adding them (reimplementing the editing in Python using 
only the standard library might be a possibility for the future; building 
the C program for $build wouldn't be a good idea and we'd like to phase 
out the remaining two tests that do use C programs for $build by subsuming 
them in conformtest).
