+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'
