[PATCH] gold: save file mtime in .gnu_incremental_inputs (version 2)

[Mikolaj Zalewski <mikolajz at google dot com>]

  In this patch I use st_mtime. However, it should be easy to plug
st_mtim for system that support it - only File_read::mtime() needs to
be changed. As I'd expect that struct timespec is also not portable,
I've defined a custom one for gold.
