-  ## Binutils Override ##

-  # Originally, there were two versions of binutils being used: the standard one and
-  # this patched one. Unfortunately, that required patches to the Xen Makefiles, and
-  # quickly became too complex to maintain. The new solution is to simply build this
-  # efi-binutils derivation and use it for the whole build process, except if
-  # enableEFI is disabled; it'll then use `binutils`.

-    doInstallCheck = false; # We get a spurious failure otherwise, due to a host/target mismatch.
-    meta.mainProgram = "ld"; # We only really care for `ld`.
