Running zpaq on an older but not ancient 64-bit Intel server aborts with an ‘Illegal instruction’ error. Turns out the build expression was using -march=native to generate distibution binaries... Change this to more conservative, portable settings which should cover ‘all’ CPUs. It may run slightly slower — but that at least implies running. As a nice side effect, all common compile flags are now back in `compileFlags` whence they came, and actually used consistently.
