Subject: Fix build of llvm-mc-assemble/disassemble-fuzzer
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ae0931ef31f33728ed62628e904d1c1f3e80d4d4;p=llvm

Fix build of llvm-mc-assemble/disassemble-fuzzer

Since these aren't built by default unless building with coverage (and
even then they aren't built for the check target) they've managed to
bit rot a little.

This just fixes the build. See llvm.org/pr34314 for the plan on making
sure these don't bit rot again.
