It would otherwise result into undefined referenecs for some functions
in the base when using the gold linker:

Fixes https://github.com/bos/double-conversion/pull/17
Previously ghc option -optl=-lm was used for packages depending on
such functions, but that could result into
fatal error: cannot mix -r with dynamic object /nix/store/7crrmih8c52r8fbnqb933dxrsp44md93-glibc-2.25/lib/libm.so.6
in some situations like profiling builds.
Patch was prepared by Michael Bishop and Niklas Hambüchen.
Closes https://github.com/NixOS/nixpkgs/pull/27584.
