HACK: disable strchr call in overlay-fs
From: Heiko Stuebner <heiko@...> Date: Thu, 3 Nov 2022 14:56:45 +0100
Commit-Message
Although the standard strchr function does _not_ use strlen at all, the compiled result with the str*-alternatives somehow wants to link against a then-nonexistent strlen symbol. All real strlen invocations everywhere else will use the correct functions though. Need to investigate what happens here. Signed-off-by: Heiko Stuebner <heiko@...>
