Pair of new macros for checking how dirent.h is implemented. Needed
to deal with versioning issues under mingw only, but won't do
any harm on other plats. The macros are:

- FP_READDIR_EOF_ERRNO
     checks what readdir() sets errno to upon reaching end of a directory.
     (that value is available as READDIR_ERRNO_EOF in mk/config.h). Up
     until recently, mingw's readdir() did set errno rather than just
     leaving it alone.
- FP_DIRENT_FLAT_LAYOUT
     checks how 'struct dirent' is defined; defines
     config.h:STRUCT_DIRENT_FLAT_LAYOUT to 1 if 'struct dirent' is terminated
     with a d_name array. Up until recently, mingw didn't define it as such.

To be hooked up to libraries/base/{include/HsBase.h,cbits/dirUtils.c} and
quite possibly merged to STABLE.
