Linker script `julia.expmap.in` references symbols that may be not defined

When trying to compile julia master on debian sid using this Make.user,
if the linker is LLVM LLD 16, there's a bit of a warnings in the output:

... and if LLVM LLD 17 is used, those warnings are errors for some reason,
which makes building impossible. This is quite unfortunate.
