[PATCH 2/2] Revert "um: clang: Strip out -mno-global-merge from USER_CFLAGS"

[Nathan Chancellor]

This reverts commit 6580c5c18fb3df2b11c5e0452372f815deeff895.

This patch is buggy, as noted in the patch linked below. The root cause
has been solved by removing '-mno-global-merge' for the entire kernel.
