From 081b4b54ff6c58be2ffcf09d42e5df8f031eacd0 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 25 Apr 2020 15:06:40 +0900 Subject: [PATCH] unicore32: do not evaluate compiler's library path when cleaning Since commit a83e4ca26af8 ("kbuild: remove cc-option switch from -Wframe-larger-than="), 'make ARCH=unicore32 clean' emits error messages as follows: $ make ARCH=unicore32 clean gcc: error: missing argument to '-Wframe-larger-than=' gcc: error: missing argument to '-Wframe-larger-than=' We do not care compiler flags when cleaning. Use the '=' operator for lazy expansion because we do not use GNU_LIBC_A or GNU_LIBGCC_A when cleaning.
