fix configure output when compiler is clang

The patch cleans up the expected errors that clutter the output of configure:

$ CC=clang ./configure
Checking for compiler... clang-6.0
clang: error: unknown argument: '-print-multiarch'
clang: error: no input files

With this patch the last two lines disappear.
