Hi.
Current lto-dump.o relies on some FE generated files as
pre-requirement. That hover delays LTO linking of the lto-dump
and so that I adjusted the dependency to LTO_OBJS which will
work as well.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin

* Make-lang.in: Relax dependency of lto-dump.o to
LTO_OBJS which will allow faster linking (mainly with LTO).
