um: do not evaluate compiler's library path when cleaning
Since commita83e4ca26a
("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. Fixes:a83e4ca26a
