[PATCH] kbuild: use -fmacro-prefix-map for .S sources compilation
From: Denys Zagorui
Date: Thu Oct 29 2020 - 07:29:25 EST
Follow-up to a73619a845d5 ("kbuild: use -fmacro-prefix-map to make
__FILE__ a relative path") commit. Assembler sources also use __FILE__
macro so this flag should be also apllied to that sources.
