Because openSUSE and many other linux distributions put all things to /usr/lib
(i586) and /usr/lib64 (x86_64) or /usr/lib32.
So it is possible to install x86 and x86_64 versions at the same time ...

It should be better to just use --libdir and make sure that LLVM_LIBDIR is set
to the result of the configure option if it's different.

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 ...
