 Don't use ld.gold when building libraries for GHCi

 Summary:
 ld.gold is buggy when using -r and a linker script.  See upstream bug
 https://sourceware.org/bugzilla/show_bug.cgi?id=22266

 This has been causing various brokenness for the GHC runtime linker,
 where we load these broken object files.

 Test Plan: Test program from #14675
