Forwarded: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/15319
Hello,
A few patches are needed to fix building ghc on hurd-any. The attached
three patches have already been applied upstream, could you apply them
to the Debian package?
Thanks,
Samuel

Fix linking against libm by moving the -lm option
For those systems that need -lm for getting math functions, this is
currently added on the link line very early, before the object files being
linked together. Newer toolchains enable --as-needed by default, which means
-lm is ignored at that point because no object requires a math function
yet. With such toolchains, we thus have to add -lm after the objects, so the
linker actually includes libm in the link.

Fix the OS string encoding for GNU/Hurd
Following https://github.com/haskell/cabal/pull/9434/files , and as seen
in the various gnu_HOST_OS usages in the source code, it is expected that
GNU/Hurd is advertised as "gnu", like the autotools do.
