Subject: [PATCH] selftests: kvm: Fix libkvm build error
commit 6e06983dde969c15eb4fdab77f0eda8b18ea28e6 upstream.
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.
"make TARGETS=kvm kselftest"
"make -C tools/testing/selftests/kvm"
