Bug 226872: lang/ghc: fails to build with lld as /usr/bin/ld
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226872



--- Description ---
-CURRENT will soon be switching to LLVM's lld linker as /usr/bin/ld, and ghc
fails to build in this case. Build log tail:
---
<no location info>:
    Warning: Couldn't figure out linker information!
	     Make sure you're using GNU ld, GNU gold or the built in OS X
linker, etc.
Segmentation fault (core dumped)
*** Error code 139

(although this probably isn't surprising for non-C ports).
