Trac #13948: fix various configure tests which break with Clang

diff --git a/SPKG.txt b/SPKG.txt

    5353   Patches `configure`, `acinclude.m4` and `configure.in`; to be applied
    5454   *after* `patches/configure.patch` (which its name should currently make
    5555   sure).  Submitted upstream (against MPIR 2.6.0; 26.02.2013).
     56 * clang-config.patch: remove one broken configure test and fix one test
     57   for Clang, see http://trac.sagemath.org/ticket/13948
    5658 * mpz__t-scan-bugfix.patch: fix trivial bug in `tests/mpz/t-scan.c` leading
    5759   to a segfault (during the test suite) with newer GCC versions.
    5860   Submitted upstream (against MPIR 2.6.0; 02.04.2013).
