One option is splitting out memusagestat and other installed executables 
not depending on glibc internals or required by the glibc testsuite into a 
separate package, built using an installed C library, as I suggested in 
<https://sourceware.org/ml/libc-alpha/2012-05/msg00682.html> and 
<https://sourceware.org/ml/libc-alpha/2012-11/msg00367.html>.
