[ Upstream commit 7e49afc03212010d0ee27532a75cfeb0125bd868 ]
Since commit a83e4ca26af8 ("kbuild: remove cc-option switch from -Wframe-larger-than="), 'make ARCH=um clean' emits an error message as follows:
$ make ARCH=um clean 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 LDFLAGS_pcap.o or LDFLAGS_vde.o when cleaning.
While I was here, I removed the redundant -r option because it already exists in the recipe.
