Subject: [PATCH 3/5] Revert "sparc: disable cancellable system, as it fails in
strange ways right now"
This reverts commit 1db4f8f8389f6a935ecd83aff7fcce5d1cf2c0f3.
It is unclear how this is breaking sparc.
With this changed 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'
