This reverts commit 1db4f8f8389f6a935ecd83aff7fcce5d1cf2c0f3.
It is unclear in which way this is breaking sparc systems.
With this change added you get following linking error:
libpthread/nptl/libpthread_so.a(pt-system.oS): In function `__libc_system':
libc/stdlib/system.c:64: undefined reference to `__wait4_nocancel'
