No, because the block happens only if ${enable_flags_setting} == yes,
and that can only occur if all CFLAGS/CXXFLAGS/CPPFLAGS/LDFLAGS are
unset. If I do ./configure CFLAGS="-O2", the whole block won't be
triggered (as intended). That block only exists to set defaults for
users running ./configure without any of the aforementioned flags set,
not for users overriding them.
