Broken linkerscript, julia fails to link with modern lld versions

Building v1.10.3 with

$ ld -v
Debian LLD 18.1.6 (compatible with GNU linkers)

https://reviews.llvm.org/D135402 This was a very contentious change to lld, but I think there might be a workaround we could do like llvm/llvm-project@fef73b8, which just defines empty versions of those symbols.

Locally, this workarounds the problem for me:

> cat Make.user
CFLAGS=-Wl,--undefined-version
CXXFLAGS=$(CFLAGS)
