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!
