./configure --disable-all-programs --enable-programs hwclock,lsblk
+tests (!):
+---------
+
+ - add a new --enable-clang-asan to ./configure
+ - add a new --asan option to tests/run.sh
+ - rename tests/run.sh --memcheck to --valgrind
+ - rename tests/functions.sh:ts_valgrind() to ts_run()
+ - improve ts_run() to be sensitive to --asan or --valgrind (etc.)
+ - use export ASAN_OPTIONS='detect_leaks=0' by default
+ - add TS_ENABLE_MEMLEAK_CHECK=yes to tests where we want to check for
+ memory leaks
+
+ Note we don't want free-before-exit code in simple utils, so no all memory
+ leaks are relevant. We care about leaks in libs, deamons, etc.
+
+ and then we can use
+
+ $ ./configure --enable-clang-asan
+ $ cd tests
+ $ ./run.sh --asan
