Subject: [PATCH 5.7 189/477] unicore32: do not evaluate compilers library path when cleaning

From: Masahiro Yamada <masahiroy@...nel.org>

[ Upstream commit 081b4b54ff6c58be2ffcf09d42e5df8f031eacd0 ]

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.

Fixes: a83e4ca26af8 ("kbuild: remove cc-option switch from -Wframe-larger-than=")
