[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=02ea469db39bb3774093cbcf5c327873febeb0f6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.02.x

Set MOREFLAGS instead of overriding CFLAGS to avoid the following build
failure raised since commit 94b66fb49cd57d0863245fbe0a3dc0833e76aad0:

/home/autobuild/autobuild/instance-6/output-1/host/lib/gcc/x86_64-buildroot-linux-uclibc/11.3.0/../../../../x86_64-buildroot-linux-uclibc/bin/ld: /tmp/ccabb8cF.o: relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC

Fixes:
