        <pre>When building current trunk version of LLVM including project/compiler-rt I see
the following error:

/bin/sh: --localize-hidden: command not found

Searching the source for this flag shows
projects/compiler-rt/lib/fuzzer/CMakeLists.txt to be the only file specifying
--localize-hidden. The error indicates that CMAKE_OBJCOPY might be empty.
Adding a cmake-message next to the line shows that the variable is indead
empty.

I suggest to use a default value ("true"?) in case the variable is not defined.



I found these matches for CMAKE_OBJCOPY in the configured build directory:
BUILD $ grep CMAKE_OBJCOPY . -riI

./projects/compiler-rt/lib/fuzzer/libcxx_fuzzer_x86_64-bins/CMakeCache.txt:CMAKE_OBJCOPY:FILEPATH=/usr/bin/objcopy
