Subject: [PATCH] powerpc/makefile: remove check on obsolete GCC versions
Date: Tue, 18 Sep 2018 05:43:17 +0000 (UTC) [thread overview]
Message-ID: <82bbb913ffd8bdc040a012152ee968cd0c6ccf4e.1537218487.git.christophe.leroy@c-s.fr> (raw)
Since commit cafa0010cd51 ("Raise the minimum required gcc version
to 4.6"), it is not possible to build kernel with GCC lower than 4.6
This patch removes checkbin tests addressing older versions of GCC.
