Testsuite runs LLVM tests even if llc isn't present
Currently configure
searches for llc
but sets SettingsLlcCommand
to llc
if it isn't found. Then both make
and Hadrian simply check whether the llc
command is non-null to determine whether LLVM tests should be run. As a result, LLVM tests are always run, even if LLVM isn't available.
