scons: force libasan to static linking
The asan(enable with --with-asan) sanitizer interpret calls to dlopen().
That replaces the RUNPATH of an executable with RUNPATH of libasan.so
after libasan.so is loaded by loader. Then it may cause some shared
libraries missing, i.e. the error messages is like
"cannot open shared object file: No such file or directory" since the
RUNPATH is no longer correct. Force the libasan to static linking
can avoid this issue since libasan.a does not have a RUNPATH, thus
the replacement will never happen.
