[PATCH v4 5/7] kbuild: move CONFIG_TRIM_UNUSED_KSYMS code unneeded for external module

From: Masahiro Yamada
Date: Fri Mar 16 2018 - 03:38:25 EST


The external module building does not need to parse this code because
KBUILD_MODULES is always set anyway.

Move this code inside the "ifeq ($(KBUILD_EXTMOD),) ... endif" block.
