Hi

This patch has been causing issues for me since switching to GCC 10.1:

  CALL    scripts/checksyscalls.sh
  CALL    scripts/atomic/check-atomics.sh
  DESCEND  objtool
  CHK     include/generated/compile.h
  HOSTCC  arch/x86/boot/tools/build
/usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: linker defined: multiple definition of '_end'
/usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: /tmp/ccEkW0jM.o: previous definition here
collect2: error: ld returned 1 exit status
make[1]: *** [scripts/Makefile.host:103: arch/x86/boot/tools/build] Error 1
make: *** [arch/x86/Makefile:303: bzImage] Error 2

Cheers
