Hi Jan,

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
Thank you for the fix!
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")
Note that this commit is only for the Makefile in 'lib', not in 'openvswitch', but I guess there is no need to backport that all along. Maybe the two modifications should be split, but I guess that's fine here.

(small detail: I guess the double whitespaces after the '=' were there to keep the alignment with the next line, so probably there should be only one now, but I don't think this alone is enough to ask for a v2!)
Apart from that:
