    This is probably a automake bug.

    When running CC=clang CXX=clang++ ./configure --enable-optimizations, configure tests for a non-existing -llvm-profdata binary:

    checking for --enable-optimizations... yes
    checking for --with-lto... no
    checking for -llvm-profdata... no
    configure: error: llvm-profdata is required for a --enable-optimizations build but could not be found.

    The generated configure script looks for "$target_alias-llvm-profdata", and $target_alias is an empty string.

    This problem is not visible on Macs, where additional checks for "/usr/bin/xcrun -find llvm-profdata" locate the binary.

    The work-around would be to specify a target when configuring.

    ../configure LLVM_PROFDATA=/<PATH TO>/llvm-profdata --enable-optimizations is also work-around.
