Subject: kernel, stage3: Disable -O2 and -flto, enable -Og
X-Git-Url: https://git.dujemihanovic.xyz/?a=commitdiff_plain;h=138126cbc8962bf148274a568916ac45454e84b7;p=nameless-os.git

kernel, stage3: Disable -O2 and -flto, enable -Og

This effectively reverts commit 99a0307 ("kernel, stage3: Enable -O2 and LTO by
default") and instead enables -Og to aid in debugging.
