Your advice does not work because following [old] code ensures to be able to run llvm-config [with right output] from build dir (= without 'make install'):

tools/llvm-config/llvm-config.in.in:55:
my ($RUN_DIR) = ($0 =~ /^(.*)\/.*$/);

tools/llvm-config/llvm-config.in.in:59:
my $ABS_RUN_DIR = abs_path("$RUN_DIR/..");

tools/llvm-config/llvm-config.in.in:69:
my $LIBDIR     = "$ABS_RUN_DIR/lib";

So push it or let it ...
