Hi

I think we started to require newer bison (although it should be checked
by configure and complained there). We aim to be compatible with 5 year
old systems, but RHEL/CentOS 6 is too old even for that.

Not sure about that, it works on CentOS 7 in our Gitlab test build.

It seems like our configure script improperly adds -flto even if CFLAGS /
LDFLAGS are expliclty set, and it is incompatible with your flags.
