Subject: [PATCH 2/2] drop _FORTIFY_SOURCE for host build
Date: Fri, 24 Jun 2022 04:30:28 -0000	[thread overview]
Message-ID: <20220506174504.10952-3-ptr@void-ptr.info> (raw)
Message-ID: <20220624043028.2yPSCE_e2pW9lP_DCSBQWhYcZdjyh54eDSSfkujMB2U@z> (raw)
In-Reply-To: <20220506174504.10952-1-ptr@void-ptr.info>

Check for _FORTIFY_SOURCE level was made for target, not for build
host. This level may not satisfy to libc on host. Fortification for
build tools looks insignificant, so just drop -D_FORTIFY_SOURCE=...
definition for host compiler.
