[llvm-dev] Ask for helpping to compile compiler-rt, thanks

[Neil Nelson via llvm-dev]

Just compiled compiler-rt OK on Ubuntu 20.04.

cd /home/*??*/Documents/llvm-project

rm -rf build

mkdir build

cd build

cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang;llvm;compiler-rt" 
-DLLVM_USE_LINKER=lld -DCMAKE_BUILD_TYPE="Release" 
-DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_ENABLE_LIBPFM=OFF 
-DRUN_HAVE_GNU_POSIX_REGEX=0 -DRUN_HAVE_THREAD_SAFETY_ATTRIBUTES=0 
-Wno-dev ../llvm &> /home/*??*/Documents/cmake.log

ninja &> /home/*??*/Documents/ninja.log

ninja.log ends with

[3790/3791] Linking CXX executable bin/llvm-readobj
[3791/3791] Generating ../../bin/llvm-readelf

There may be some other aspects that need tweaking but let's start with 
the above.

Let's see your command sequence,

Change ?? as needed.
