Subject: [PATCH 0/4] e2fprogs: fun with compilers

Hi all,

This patch series enhances the e2fsprogs build system to allow us to
take advantage of new compiler technologies.  The first patch enables
LTO, which can perform executable-wide code optimizations (particularly
eliminating dead functions).  The three patches after that enable the
sanitizers for undefined behavior, memory access, and thread safety.
With these sanitizers we can collect runtime reports about questionable
C code, memory access problems, and thread safety problems (though at
the moment e2fsprogs isn't heavily threaded).
