 Module Name:	src
 Committed By:	maya
 Date:		Tue May  7 18:12:53 UTC 2019
 
 Modified Files:
 	src/lib/libpthread: Makefile
 
 Log Message:
 Replace the link command for libpthread.a so that we create a single section
 with all the libpthread symbols in it.
 This makes -lpthread behave like to -Wl,--whole-archive -lpthread.
 
 This avoids a situation where threaded static binaries use some libc thread
 stubs, which are racy.
 
 Fixes PR lib/54001: call_once2_32, call_once2_static test cases failing on
 amd64 since gcc7 import.
 
 Suggested by Jonathan Wakely, thanks!
