for the next gnulib update

[Bruno Haible]

Hi,

A couple of changes in gnulib on 2019-07-15 [1] need updates on the coreutils
side, the next you update the gnulib used by coreutils.


1) The 'pthread' module is now a convenience module that includes
functionality that coreutils does not need (such as thread-specific storage).
Suggested patch:

diff --git a/bootstrap.conf b/bootstrap.conf
index 4926152..018bc4e 100644
--- a/bootstrap.conf
+++ b/bootstrap.conf

2) gnulib no longer defines GNULIB_defined_pthread_functions. This macro was
not documented and has been removed. Suggested patch:

diff --git a/src/sort.c b/src/sort.c
index d812aa9..360a1f1 100644
--- a/src/sort.c
+++ b/src/sort.c

-# define pthread_sigmask(how, set, oset) sigprocmask (how, set, oset)
-#endif
-
 #if !defined OPEN_MAX && defined NR_OPEN
 # define OPEN_MAX NR_OPEN
 #endif


Rationale: pthread_sigmask is already handled by gnulib's <signal.h>
override.
