From 829889ac4a7d26858860c297e64051bd27ce8fbe Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 12 Nov 2018 11:35:19 +0900 Subject: x86/um: Remove -fno-unit-at-a-time workaround for pre-4.0 GCC Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6") bumped the minimum GCC version to 4.6 for all architectures. '$(call cc-option,-fno-unit-at-a-time)' is now dead code since '$(cc-version) -lt 0400' is always false. Remove it.
