I'm confused here. LDFLAGS seems to contain "-Werror=lto-type-mismatch" which the linker does not recognize so the configure check fails!? What am I missing, or can it be that the tinderbox build is not configured properly?

/usr/lib/gcc/x86_64-pc-linux-gnu/15/../../../../x86_64-pc-linux-gnu/bin/ld: use the --help option for usage information
```

It's getting passed after -Xlinker so it gets interpreted as an actual linker option, not an option for the compiler driver (where it's fine and correct, even).

In general, LDFLAGS these days should be taken as args to the driver. But you could workaround it by filtering LDFLAGS for -W* if the build system is too hard to fix.
