Hi Michael,

I believe the following diff will function as a workaround for this 
issue (untested by me):

diff --git a/lib/clang/llvm.build.mk b/lib/clang/llvm.build.mk
index 5aff7081fb76..730b1131068e 100644
--- a/lib/clang/llvm.build.mk
+++ b/lib/clang/llvm.build.mk
@@ -104,7 +104,7 @@ CFLAGS+=    -fdata-sections
.if ${LINKER_TYPE} == "mac"
LDFLAGS+=      -Wl,-dead_strip
.else
-LDFLAGS+=      -Wl,--gc-sections
+LDFLAGS+=      -Wl,--gc-sections,-m,elf64lriscv_fbsd
.endif

CXXSTD?=       c++14

CC'ing Jess, who knows the full story here.

Cheers,
Mitchell
