Fix the following build error from "make TARGETS=kvm kselftest": libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC This error is seen when build is done from the main Makefile using kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS are defined. When build is invoked using: "make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS aren't defined. There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the check to determine if --no-pie is necessary, which is the case when these two aren't defined when "make -C tools/testing/selftests/kvm" runs. Fix it by simplifying the no-pie-option logic. With this change, both build variations work.
