Comment (by leif):
To be more precise:
* Singular dropping / ignoring `*FLAGS` (in this case, `-flto`, or
`LDFLAGS` ''from compiler link commands'') isn't nice, likewise ignoring
`CXXFLAGS` in some compile commands, and should probably get fixed and
reported upstream, but ''should '''not break''' the build'' (at least if
only `-flto` isn't passed to the compiler).
* The error we get with LTO (when enabled during the link phase), which
makes the build ''fail'', is a '''GCC bug''', and should get reported GCC
upstream.
