Package build environments like Fedora rpmbuild introduced hardening
options (e.g. -pie -Wl,-z,now) by passing a -spec option to CFLAGS
and LDFLAGS.
ynl Makefiles currently override CFLAGS but not LDFLAGS, which leads
to a mismatch and build failure:
CC sample devlink
/usr/bin/ld: devlink.o: relocation R_X86_64_32 against symbol `ynl_devlink_family' 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
Extend CFLAGS to support hardening options set by build environment.
