Package build environments like Fedora rpmbuild introduced hardening
options (e.g. -pie -Wl,-z,now) by passing a -spec option to CFLAGS
and LDFLAGS.
Some Makefiles currently override CFLAGS but not LDFLAGS, which leads
to a mismatch and build failure, for example:
/usr/bin/ld: /tmp/ccd2apay.o: relocation R_X86_64_32 against
`.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: failed to set dynamic section sizes: bad value
collect2: error: ld returned 1 exit status
make[1]: *** [../../lib.mk:222: tools/testing/selftests/net/lib/csum] Error 1
openvswitch/Makefile CFLAGS currently do not appear to be used, but
fix it anyway for the case when new tests are introduced in future.
Fixes: 1d0dc857b5d8 ("selftests: drv-net: add checksum tests")
