commit 2a973ab7f1a6f6cd9be1c7257fd7b5d331515eab
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Wed Sep 12 10:30:46 2018 -0300

    posix: Add internal symbols for posix_spawn interface
    
    This patch adds internal hidden definition for mostly of the posix_spawn
    function so it can be used internally on both popen and system
    implementations.
    
    Checked on x86_64-linux-gnu.
    
    	* include/spawn.h (__posix_spawn, posix_spawn_file_actions_addclose,
    	__posix_spawn_file_actions_adddup2, __posix_spawn_file_actions_destroy,
    	__posix_spawn_file_actions_init, __posix_spawnattr_init,
    	__posix_spawnattr_destroy, __posix_spawnattr_setflags,
    	__posix_spawnattr_setsigdefault, __posix_spawnattr_setsigmask): New
    	prototype.
    	* posix/spawn.c (__posix_spawn): Add libc_hidden_def.
    	* posix/spawn_faction_addclose.c
    	(__posix_spawn_file_actions_addclose): Add hidden definition.
    	* posix/spawn_faction_adddup2.c
    	(__posix_spawn_file_actions_adddup2): Likewise.
    	* posix/spawn_faction_destroy.c
    	(__posix_spawn_file_actions_destroy): Likewise.
    	* posix/spawn_faction_init.c (__posix_spawn_file_actions_init):
    	Likewise.
    	* posix/spawnattr_destroy.c (__posix_spawnattr_destroy): Likewise.
    	* posix/spawnattr_init.c (__posix_spawnattr_init): Likewise.
    	* posix/spawnattr_setdefault.c (__posix_spawnattr_setsigdefault):
    	Likewise.
    	* posix/spawnattr_setflags.c (__posix_spawnattr_setflags): Likewise.
    	* posix/spawnattr_setsigmask.c (__posix_spawnattr_setsigmask):
    	Likewise.
