coreutils: bump to version 8.23

Add hash file. patches 01 & 02 are now upstream so remove them.
Patch 01 isn't required any more (no posix_spawn usage).
Patch 02 is upstream.
Patch 03 retooled for 8.23 and renamed to 01.

-* m4/spawn_h.m4 (gl_HAVE_POSIX_SPAWN): use AC_SEARCH_LIBS,

-* modules/posix_spawn: Reference the substituted LIB.
-
-Patch status: suggested by gnulib maintainer
-(http://article.gmane.org/gmane.comp.lib.gnulib.bugs/33610), not in upstream
-gnulib yet
-
-This issue should be fixed in coreutils version 8.23.

-Fix thread detection with uClibc in timer_time.m4
-
-The timer_time.m4 gl_TIMER_TIME function determines which libraries
-need to be linked to get access to the timer function, generally -lrt
-for Linux systems. On platforms where threads are used, librt
-typically uses thread functions from libpthread.
-
-However, the test to determine whether the platform has thread or not
-is incorrect: it assumes that if the C library is uClibc, then threads
-are not available. This is actually not true: uClibc has configurable
-thread support, and when thread support is available, librt calls
-libpthread functions.
-
-This is important when static linking is used, because otherwise only
--lrt is used at link time, which fails because librt calls undefined
-thread functions. Both -lrt and -lpthread must be passed.
-
-This problem is fixed by making the uClibc thread detection a bit
-smarter, thanks to the usage of the __HAS_NO_THREADS__ macro defined
-in <bits/uClibc_config.h>, which itself is included by <features.h>.
