there was already parts of that in the makefile that would require
running "make gb_GCOV=YES" - but that alone was not enough, you were
also kinda expected to set LDFLAGS on the commandline (or at least it
had bitrotted to this state) - so just make it into a proper configure
switch.
Building with lto fails at least on baseline with

[…many more of those with incrementing references…]
So for now warn if both are used.
