test: rebuild the test programs when localconf changes

../localconf overrides CC, CXX and CCFLAGS but was not a prerequisite of
anything test/Makefile builds with them, so editing it recompiled
nothing and left the tree able to link objects from two compilers.
Under -flto that surfaces at link time as "plugin needed to handle lto
object", which names neither localconf nor the compilers.

test/Makefile gains BUILD_CONF and uses it wherever ../makeflags
appeared in a prerequisite list, including the link rules, and the .dep
rules that previously depended on neither file.  localconf is optional
and has no rule to create it, so $(wildcard) names it only when it
exists.

The same change to lib/Makefile and src/Makefile is already on next.
Only test/Makefile is left here: next carries a much smaller set of test
programs, so its version of this file converted only the rules that
exist there, and the rules this branch adds still needed converting.

Verified that an unchanged tree still does no recompiles, that touching
localconf now rebuilds, and that `make test' and `make build-check' both
pass afterwards.
